+	* read.c (read_all_makefiles): Use allocated_variable_expand to expand
+	`$(MAKEFILES)', since the results are used across calls to
+	read_makefile, which could clobber them.
+
+Wed Jan 23 00:24:10 1991  Roland McGrath  (roland at cygint.cygnus.com)
+
+	* main.c (main): Call install_default_implicit_rules after reading
+	makefiles, not before.
+	* default.c (install_default_implicit_rules): If a suffix-rule file
+	entry has cmds, don't give it any from default_suffix_rules.
+
+Fri Jan 17 17:39:49 1991  Roland McGrath  (roland at albert.ai.mit.edu)
+

+
+	* job.c (search_path): Take new arg, place to put full pathname (rather
+	than mallocing it).
+	(exec_command): Pass it, using auto storage.
+
+	* main.c (print_version): Updated copyright years.
+
+Wed Jan  8 19:46:19 1991  Roland McGrath  (roland at albert.ai.mit.edu)
+
+	* job.c [_POSIX_SOURCE]: Just #include <sys/wait.h>, and define macro
+	WAIT_NOHANG in terms of waitpid.
+	[!_POSIX_SOURCE && (HAVE_SYS_WAIT || !USG)]: Don't #include <signal.h>
+	(make.h does).
+	Define macro WAIT_NOHANG in terms of wait3.

+
+	* default.c (default_variables): Rename 2nd LINK.s defn to LINK.S.

+Fri Dec 14 15:05:25 1990  Roland McGrath  (roland at albert.ai.mit.edu)
+
+	* vpath.c (selective_vpath_search): Check for makefile-mentioned before
+	checking for actual existence.  The old order loses if the containing

+
+	* rule.c (convert_to_pattern): Don't look at the target constructed for

+
+Mon Dec 11 01:19:29 1990  Roland McGrath  (roland at albert.ai.mit.edu)
+
+	* default.c [M_XENIX]: For rules that are different for Xenix, use the
+	generic Unix version #ifdef __GNUC__.
+
+	* main.c [M_XENIX]: Use USGr3-style setvbuf call.
+

+
+	* make.h [STDC_HEADERS || __GNU_LIBRARY__ || _POSIX_SOURCE]: Use
+	ANSI <string.h> and names for str/mem functions.
+	Use <stdlib.h> to declare misc fns rather than explicit decls.
+	[_POSIX_SOURCE]: Don't declare kill (<signal.h> will).
+	Include <sys/types.h> before <signal.h> because some braindead
+	nonconformant 1003.1 implementation needs it.
+	* misc.c: Don't declare malloc, realloc.  Do it in make.h.
+	* arscan.c, glob.c: Use sequence for string fns from make.h verbatim.
+	* make.h (S_ISDIR, S_ISREG): Declare if necessary.

+
+Tue Nov 28 16:00:04 1990  Roland McGrath  (roland at churchy.ai.mit.edu)
+
+	* arscan.c (ar_name_equal) [APOLLO]: Don't do `.o' hacking.  On Apollos
+	the full file name is elsewhere, and there is no length restriction (or
+	so I'm told).
+
+Thu Nov 23 17:33:11 1990  Roland McGrath  (roland at albert.ai.mit.edu)
+
+	* load.c [hp300 && BSD] (LDAV_CVT): Define for this system.

+
+	* main.c (define_makeflags): When there are no flags to write, make

+	CMDS->lines_recurse.
+
+	* Version 3.58.11.
+
+	* job.c (start_job): Don't always increment CHILD->command_line!  Only

+
+	* GNUmakefile [ARCH]: Give explicit rule for remote.{c,dep} to use

+Wed Sep 19 02:30:36 1990  Roland McGrath  (roland at churchy.ai.mit.edu)
+
+	* commands.h (struct commands): New member `ncommand_lines', the number
+	of elts in `command_lines' et al.
+	* commands.c (chop_commands): Set `ncommand_lines' elt of CMDS, and
+	don't put a nil pointer at the end of `command_lines'.
+	* job.h (struct child): New member `command_lines' to hold
+	variable-expanded command lines.
+	* job.c (new_job): Store expanded command lines in `command_lines'
+	member of new child.  Don't clobber FILE->cmds.
+	(start_job): Use CHILD->command_lines in place of
+	CHILD->file->cmds->command_lines.
+
+	* variable.h, variable.c, job.c, expand.c: Undo yesterday's change,

+
+	* job.c (start_job): Don't variable-expand each command line.
+	(new_job): Do them all here, storing the expansions in the array.

+Tue Sep 18 01:23:13 1990  Roland McGrath  (roland at churchy.ai.mit.edu)
+
+	* variable.h (struct variable): Remove `expanding' member.
+	* variable.c (define_variable_in_set): Don't initialize it.
+	* expand.c (struct variable_expanding): New type, a linked list
+	containing `struct variable' pointers.

+	being expanded.
+	(recursively_expand): Don't test and set `expanding' member.
+	Instead, run through the `variables_expanding' chain looking for a link
+	referring to V to find self-reference.  Add a new link to the chain,
+	describing V, before recursive expansion, and pop it off afterward.
+	* job.c (child_handler): Save `variables_expanding' and clear it before
+	calling start_job, and restore it afterward.  This avoids major lossage
+	when the SIGCHLD comes in the middle of variable expansion.
+
+Mon Sep 17 14:46:26 1990  Roland McGrath  (roland at geech.ai.mit.edu)
+
+	* job.c, commands.c: Don't define sigmask.

+	(block_signals) [USG]: Set it.
+	(unblock_signals) [USG]: Clear it.
+	(child_handler) [USG]: Don't complain about unknown children if
+	`unknown_children_possible' is set.
+
+	* read.c (do_define): Make sure there's enough space for the newline,
+	so we don't write off the end of allocated space.
+
+	* arscan.c (ar_name_equal): Fixed to work when MEM is AR_NAMELEN-1 but
+	NAME is not the same length.
+
+Sat Aug 25 16:17:14 1990  Roland McGrath  (roland at geech)
+
+	* job.c (construct_command_argv_internal): Use a static char array for
+	a constant, since old C has no auto aggregate initializers.
+
+Thu Aug 23 16:11:03 1990  Roland McGrath  (roland at churchy.ai.mit.edu)
+
+	* job.c (search_path): If PATH is nil or "" use a default path.
+
+Wed Aug 22 01:05:32 1990  Roland McGrath  (roland at churchy.ai.mit.edu)
+
+	* Version 3.58.9.
+

+	(child_execute_job): Don't take FILE arg, and don't pass path and shell
+	to exec_command.

+	* function.c (expand_function: `shell'): Ditto.
+	* main.c (main): Don't pass path and shell to exec_command.
+
+Fri Aug 17 23:17:27 1990  Roland McGrath  (roland at geech)
+
+	* job.c (construct_command_argv_internal): New fn broken out of
+	construct_command_argv.  Takes strings SHELL and IFS instead of doing
+	variable expansion for them.  Recurse to make an argv for SHELL,
+	passing SHELL==0.  When SHELL==0, don't recurse for shell argv; make a
+	simple one using /bin/sh.
+	(construct_command_argv): Do the variable expansions and call above.
+
+Thu Aug 16 19:03:14 1990  Roland McGrath  (roland at geech)
+
+	* read.c (multi_glob): For ~USER/FILE, if USER isn't found, don't
+	change the file name at all.
+
+Tue Aug  7 18:33:28 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* function.c (expand_function: `suffix'/`notdir'): Don't kill the last
+	space if we never wrote one.
+
+	* function.c (expand_function: `suffix'): Retain the dot, like the
+	documentation says.
+
+Mon Aug  6 14:35:06 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.58.8.
+
+	* main.c (decode_switches): For positive_int and floating cases, move
+	SW past the arg (and don't set it to ""), so another switch can follow.
+
+Fri Aug  3 00:43:15 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* job.c (child_execute_job): Use unblock_signals instead of

+	fatal_error_signal.
+	(main): Set it.
+	* job.c ({block,unblock}_children): Renamed to {block,unblock}_signals.
+	Block/unblock both child signal and signals in fatal_signal_mask.
+	(children_blocked_p_{stack,max,depth}, {push,pop}_children_blocked_p):

+	* commands.c (fatal_error_signal), job.c (wait_for_children, new_job,
+	child_execute_job, main, log_working_directory), function.c
+	(expand_function: `shell'), job.h: Rename {push,pop}_children_blocked_p
+	to {push,pop}_signals_blocked_p.
+	* job.c (child_handler): Call {block,unblock}_signals instead of just
+	{block,unblock}_remote_children.  We need to block the fatal signals.
+
+Thu Aug  2 22:41:06 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* main.c, function.c: Fixed typos in comments.

+
+Fri Jul 20 15:30:26 1990  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

+	empty.
+
+Wed Jul 18 11:26:56 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.58.6.
+
+	* commands.c (set_file_variables): Fixed computation for ^F/?F elt len.
+
+Sat Jul 14 13:41:24 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* job.c (construct_command_argv): Always use
+	allocated_variable_expand_for_file instead of variable_expand_for_file
+	because we might be called from inside a variable expansion (for the
+	`shell' function).
+
+	* function.c (expand_function: `shell'): Free the arglist's storage
+	correctly.  construct_command_argv only allocates ARGV and ARGV[0].
+
+	* job.c (children_blocked_p_idx): Renamed to children_blocked_p_depth.
+	(push_children_blocked_p, pop_children_blocked_p): Use ..._depth

+
+Wed Jul 11 15:35:43 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* make.h (SIGNAL): New macro to replace `signal' calls.  Does arg and

+
+Fri Jul  6 00:00:38 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* ar.c (ar_member_date, ar_touch): Pass 2nd arg to f_mtime.
+
+	* read.c (read_makefile): Search the include path for MAKEFILES
+	variable makefiles (TYPE == 1), like it says in the manual.
+
+	* file.h (struct file), main.c (struct command_switch): Remove trailing
+	commas from enums.
+
+	* commands.c (execute_file_commands): Remove unused variables.

+	* ar.c: Declare ar_name_equal.

+	VPATH search if we're searching, and change the ar ref accordingly.
+
+	* ar.c (ar_parse_name): New global fn to parse archive-member
+	references into the archive and member names.
+	(ar_member_date, ar_touch): Use it.
+	* make.h: Declare it.

+
+	* vpath.c (selective_vpath_search): Only accept prospective files that
+	don't actually exist yet are mentioned in a makefile if the file we are
+	searching for isn't a target.
+
+Wed Jul  4 04:11:55 1990  Roland McGrath  (mcgrath at helen.Berkeley.EDU)
+
+	* remake.c (update_goal_chain): Do check_renamed after calling

+	(check_dep): Ditto after update_file.
+
+	* file.c (rename_file): Prettied up long message for merging cmds.
+
+	* remake.c (update_file_1): Get each dep file's modtime, and allow for
+	it being renamed, before checking for a circular dep, since a renaming
+	may have introduced one.
+
+Tue Jul  3 18:15:01 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* ar.c (ar_touch): Don't free ARNAME since enter_file holds onto the
+	storage.
+
+	* function.c (string_glob): Don't leave a trailing space.
+
+	* read.c (do_define): Allow leading whitespace before `endef'.
+
+Mon Jul  2 14:10:16 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* implicit.c (pattern_search): No longer take NAME arg.  Instead take
+	ARCHIVE flag.  If ARCHIVE is nonzero, FILE->name is of the form
+	"LIB(MEMBER)"; rule for "(MEMBER)" is searched for, and LASTSLASH is
+	set to nil.  Since NAME was only non-nil when it was the archive member
+	name passed by try_implicit_rule, this change easily allows turning off
+	LASTSLASH checking for archive members without excessive kludgery.
+	(try_implicit_rule): Pass ARCHIVE flag instead of file name.
+
+	* Version 3.58.5.
+
+	* commands./c (set_file_variables): Don't kill last char of $(^D) elts.
+
+Sat Jun 30 00:53:38 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+

+
+	* arscan.c (ar_scan) [sun386 && PORTAR == 1]: Treat like USGr3.
+
+Wed Jun 27 14:38:49 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* main.c (main): Put a newline on the debugging message when deciding
+	not to remake a makefile to avoid a possible loop.
+	Only decide not to remake makefiles that have commands (as well as
+	being targets and having no deps).

+
+	* glob.c: Replaced with updated version from djm.
+	* glob.c: Check macro DIRENT instead of _POSIX_SOURCE for <dirent.h>.

+
+	* vpath.c (vpath_search): Don't stop the loop if a pattern matches but

+	explicitly blocking and unblocking children.
+	* function.c (expand_function: `shell'): Don't unblock children.  The
+	push-pop sequence in wait_for_children makes it unnecessary.
+

+
+	* read.c (do_define): Don't include the last newline in the definition.

+	do this anyway (and lack of declarations is harmless).
+
+	* remote-customs.c: Renamed to remote-cstms.c for System V.
+	* remote.c [CUSTOMS]: Changed accordingly.
+
+Sun May 13 14:38:39 1990  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* GNUmakefile: Use same cmds for doc tar.Z as for dist tar.Z (so the

+	* GNUmakefile: Made `.dep' files be architecture-specific too.
+
+	* main.c (main, log_working_directory) [USG]: Block children around
+	calls to `getwd' (actually `getcwd' on USG), because that function
+	sometimes spawns a child running /bin/pwd on USG.
+
+Tue Jan 30 14:02:50 1990  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* function.c (subst_expand): Pay attention to SUFFIX_ONLY, putz.

+	* file.c (rename_file): Completely rewritten.  Renames in place if

+	`make' itself (instead of the manual) has various chapters.

+	`patsubst', use node `Text Functions', not `Functions'.
+	Add an xref about `patsubst' after description of $(var:a%b=c%d).
+	(Functions: Syntax of Functions): Explain why mixing delimiters in
+	function/var refs is unwise.  Clarify fn arg evaluation order.
+	(Options): Reworded sentence about `-e'.
+	(Implicit: Implicit Variables): Don't say `RM' is unused.
+	Say the dflt values for the flag vars is empty unless otherwise noted,
+	since some have defaults.
+	(Implicit: Pattern Rules: Pattern Examples): Clarified use of $< and $@
+	in first example.
+	(Implicit: Last Resort): Don't say the .DEFAULT example creates files
+	"silently".  It's automatic, but not silent.
+	(Implicit: Search Algorithm): Fixed confusing ungrammatical sentence
+	for item 5.1.

+	(Archives: Archive Symbols): Note that GNU `ar' deals with this

+	search path (broken out of exec_command).
+	(exec_command): Take fourth arg, the shell program to use (if

+	(child_execute_job): Pass shell program to exec_command.
+	* main.c (main): Ditto.
+
+	* main.c (main): Don't write a message if exec_command returns, because

+
+	* remake.c (update_file_1): Took code to force remake of nonexistent

+	deps.  In version 4, I think removing this test completely will
+	implement the new feature that if a: b and b: c and c is newer than a,
+	b need not be remade.

+	being updated.  (The exact opposite test was here before; why???)

+
+	* main.c (main) [hpux]: hpux == HPUX.

+	then try to free them.

+
+	* main.c (main): Make an array of the mtimes of the makefiles before
+	updating them, and compare their file_mtimes against this later.  Don't
+	re-exec if a makefile was successfully updated but didn't change.  If a
+	makefile failed to be remade and no longer exists, die.  If a makefile
+	failed to be remade, but changed anyway, re-exec.  If a makefile failed

+	Make will grok (except for FP/int values and new flags).
+
+	* job.c (child_execute_job): Don't use the shell's -c option.
+	Also fixed an off-by-one bug in the ARGV -> shell arg list copying.

+

+
+Sat Sep 16 12:38:58 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+

+
+	* GNUmakefile (dist): Depend on default and doc.

+
+Thu Sep  7 16:46:26 1989  Roland McGrath  (mcgrath at paris.Berkeley.EDU)

+	variable.c.
+	* file.c (lookup_file, enter_file, rename_file): Use it.
+	* dir.c (find_directory, dir_file_exists_p, file_impossible_p): Ditto.

+
+	* load.c [LDAV_BASED] (load_average): Check for == -1, rather than < 0
+	to see if lseek fails.  On some systems, `avenrun' is at an offset >

+Mon Sep  4 11:07:58 1989  Roland McGrath  (mcgrath at saffron.Berkeley.EDU)

+

+
+	* Version 3.55.1 (alpha).
+
+	* function.c (string_glob): Don't add spaces after file names that
+	aren't added.  (Also means don't add spaces without checking the size
+	of the buffer.)
+
+	* remake.c (update_goal_chain): Don't remove makefiles with cmds and no
+	deps from the chain.
+	* main.c (main): Do it here, before calling update_goal_chain.
+
+	* remake.c (update_goal_chain): When updating fails, change STATUS even
+	if MAKEFILES is set.  Also stop remaking when updating fails if not
+	under -k and MAKEFILES is not set.
+
+	* remake.c (remake_file, update_file_1, notice_finished_file),
+	commands.c (execute_file_commands), make.h, commands.h: The functions
+	remake_file, notice_finished_file, and execute_file_commands no longer
+	return values, and their callers no longer expect values returned.
+
+	* remake.c (notice_finished_file): Don't set FILE's modtime to now if
+	it is a non-target with no commands.
+
+Fri Sep  1 00:04:39 1989  Roland McGrath  (mcgrath at saffron.Berkeley.EDU)

+	replace it with the name stored in read_makefiles by read_makefile.
+
+	* remake.c (update_file_1): Don't decide not to remake if FILE has no
+	cmds and no deps actually changed if FILE doesn't have any deps.
+
+	* file.c (remove_intermediate): Remove precious files that also have
+	the `dontcare' flag set.
+
+	* remake.c (update_file_1): Don't always remake if FILE has cmds but no
+	deps; only if FILE is double-colon.  (I don't know why this should be
+	done for double-colon targets, but that's what Unix make does.)
+
+	* load.c [LDAV_BASED] (load_average): Write error messages if the
+	various system calls fail.  Keep track of if we've failed before.
+	The first time we fail, write a message saying -l won't be enforced.
+	The first time we succeed after having failed, write a message saying
+	-l will be enforced again.
+
+	* remake.c [USG]: Don't #include <sys/file.h>
+
+	* load.c [generic Unix LDAV_BASED]: #include <fcntl.h> #ifdef USG,
+	else <sys/file.h> instead.
+
+	* job.c [USG && !USGr3 && !HAVE_DUP2]: Remove redundant
+	#include <errno.h> and declaration of `errno'.
+	[...] (dup2): Fixed so it won't always lose.
+
+	* default.c (default_suffix_rules: .texinfo.dvi): Copy, rather than
+	move, the aux and index files, so the TeX run can use them.
+
+	* compatMakefile: Remove redundant comment.
+
+	* load.c [generic Unix LDAV_BASED]: Include <a.out.h> instead of
+	<nlist.h>, since the `struct nlist' declaration in <nlist.h> varies
+	more than the one in <a.out.h>.
+	(load_average): Use the `n_un.n_name' field of the `struct nlist',
+	since the <a.out.h> declaration uses the union.
+
+	* main.c (main): For the temporary files made for stdin makefiles, set
+	the `intermediate' and `dontcare' flags.
+	* file.c (remove_intermediates): Don't print any messages for files
+	whose `dontcare' flag is set.  (The only files that will be
+	intermediate and `dontcare' will be the temporary files made for stdin
+	makefiles.)
+
+	* job.c (exec_command): Made global.
+	* job.h: Declare it.
+	* main.c (main): Use exec_command when re-execing.
+
+	* make.h: Declare environ.
+	* make.c: Don't.
+
+	* job.c (child_execute_job): New function to perform everything done in
+	the child side of a fork (for a job or `shell' function).
+	(start_job): Call it.
+	* job.h: Declare construct_command_argv and child_execute_job.

+	separately and define all those that aren't defined.
+
+Sat Aug 26 15:13:21 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* ar.c (ar_name): Return zero for `(foo)'.
+
+	* Version 3.55.
+
+	* make.texinfo (Rules: Multiple Targets): Make this node's `next'
+	pointer point to `Static Pattern'.
+	* make.texinfo (Makefiles: MAKEFILES Variable): Make this node's `prev'
+	pointer point to `Makefile Names'.
+
+	* make.1: Renamed to make.man.
+	* compatMakefile: Define `mandir' and `manext'.
+	(install): Depend on $(mandir)/make.$(manext).
+	($(mandir)/make.$(manext)): Depend on make.man and copy it to $@.
+	($(bindir)/make): Use `make' rather than $<; so Unix make can grok it.
+
+Thu Aug 24 03:35:48 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* variable.c (target_environment): Allow variables that start with

+
+Wed Aug 23 22:50:32 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* variable.c (target_environment): Reject variables that don't start
+	with letters.
+
+Tue Aug 22 04:14:29 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* GNUmakefile (make-$(version).tar.Z): Put make.1 (the Unix manual
+	page) in the tar file.
+
+	* variable.c (target_environment): Don't write variables with origin
+	o_default (i.e., ones from default.c).
+	* make.texinfo (Commands: Recursion: Variables/Recursion): Document
+	that default variables are not put in the environment.
+
+	* remake.c (update_file_1): Remake all targets with commands but no
+	deps.
+
+Sat Aug 19 06:03:16 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* remake.c (update_file_1): In the final loop, set the deps'
+	`changed' members if they are newer than FILE.
+
+	* remake.c (update_goal_chain): Under -d, print a message if we decide
+	not to remake a makefile so as to avoid a possible infinite loop.
+
+Fri Aug 18 20:30:14 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* remake.c (remake_file): Cleaned up.
+
+	* commands.c (execute_file_commands): If the commands are empty, set
+	FILE->update_status to zero before returning.
+
+	* remake.c (notice_finished_file): Set `last_mtime' fields to zero
+	instead of calling name_mtime; file_mtime will do that later if anybody
+	cares.
+
+Thu Aug 17 10:01:11 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* make.texinfo (Rules: Wildcards: Wildcard Examples): Give this node a
+	`prev' pointer.
+
+	* Version 3.54.9 (alpha).
+
+	* make.texinfo: Fixed some @nodes.
+
+	* remake.c (check_dep): Don't set *MUST_MAKE_PTR if FILE doesn't exist
+	after running update_file.
+
+	* remake.c (notice_finished_file): If FILE has no commands, pretend its
+	modtime is now.
+
+	* remake.c (update_file_1): In the loops that call update_file on the
+	deps, compare modtimes before and after (unless deps are still being
+	made) and set the deps' `changed' members.  Do not set the `changed'
+	members in the loop that prints the newer/older debugging messages.
+	* remake.c (update_file_1): If no deps changed and FILE has no
+	commands, decide it doesn't need remaking.
+
+	* remake.c (update_file_1): Print a debugging message if we take
+	commands from default_file.
+
+	* make.texinfo (Rules: Directory Search: Selective Search): Removed
+	note about warning for `vpath' with a constant pathname, since it isn't
+	warned about anymore.
+
+	* remake.c (update_goal_chain): If MAKEFILES, remove makefiles which
+	are targets and have no deps.
+	* make.texinfo (Makefiles: Remaking Makefiles): Document that makefiles

+	* job.c (exec_command): If the execve fails with ENOEXEC (Exec format
+	error), return instead of exiting the child process.
+
+	* job.c (start_job): In the child side, if exec_command fails, try
+	using the shell.
+
+	* job.c (start_job): In the child side, call unblock_children instead
+	of sigsetmask.

+	files_remade for non-phony files.
+
+	* rule.c (intall_pattern_rule): Use find_percent.
+
+	* vpath.c (vpath_search): Pass the `percent' members to
+	pattern_matches.
+
+Mon Aug 14 23:30:24 1989  Roland McGrath  (roland at apple-gunkies.ai.mit.edu)
+
+	* vpath.c (struct vpath): New member `percent', to hold a pointer into
+	the pattern where the % is.
+	(construct_vpath_list): Call find_percent on the pattern and set the
+	new `percent' member.

+	patterns.

+	* function.c (pattern_matches): Take new arg PERCENT, a pointer into
+	PATTERN where the % is.  If PERCENT is nil, copy PATTERN into local
+	space and run find_percent on it.
+	(expand_function: `filter', `filter-out'): Pass new arg to
+	pattern_matches.
+	* read.c (record_files): Pass PATTERN_PERCENT to pattern_matches for

+	(create_pattern_rule): Take new arg TARGET_PERCENTS, nil or an array of
+	pointers into the corresponding elements of TARGETS, where the %s are.

+
+	* Version 3.54.8.
+
+	* README.templatate, README-doc.template: New files, turned into README
+	and README-doc to go into the two distribution tar files.
+	* GNUmakefile: Added a rule to edit the version number in
+	README.template and README-doc.template, producing README and
+	README-doc.
+
+	* remake.c (update_goal_chain): If -n or -q is in effect for a
+	makefile, and it got updated, don't change STATUS, so we can still
+	return -1 (meaning nothing was done).  This avoids an infinite loop on
+	"make -n Makefile".
+
+Sat Aug 12 23:14:24 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* remake.c (notice_finished_file): Treat -q the same as -n.
+
+	* remake.c (update_goal_chain): Fixed handling of return from
+	update_file.  If -n or -q is in effect, ignore it.
+
+	* job.c (start_job): Don't test for -t.  We should never get called in
+	that case.
+
+Fri Aug 11 04:09:14 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* function.c (expand_function): Removed unused variables.
+	(handle_function): Removed unused variable.
+
+	* main.c (main): Removed unused variable.
+
+Wed Aug  9 09:37:10 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* Version 3.54.7.
+
+	* remake.c (notice_finished_file): If FILE's modtime actually changed,
+	increment files_remade.
+	(remake_file): Don't increment files_remade.
+
+	* remake.c (update_file): Don't print "up to date" messages for
+	phony files.
+
+	* job.c (child_handler): Don't set C->file->update_status to 1 if
+	start_job returns nonzero under -n or -t.
+
+	* expand.c (variable_expand): Count parens in $(foo:a=b) refs.
+
+	* main.c: Removed old declaration of `glob_tilde' (which hasn't existed
+	for a few months).
+
+Tue Aug  8 23:53:43 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* job.c (exec_command): Fixed to not ignore the last path component and

+Fri Aug  4 15:58:19 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* remake.c (library_file_mtime): Look for libLIB.a, not /libLIB.a.

+
+	* job.c [HAVE_SYS_WAIT or not USG]: If WIFSIGNALED is not defined by

+
+Tue Aug  1 19:25:34 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* remake.c (remake_file): If FILE has no commands and is a target,
+	don't set its time to now.  The time gets reset by notice_finished_file
+	anyway, and it isn't needed since check_dep checks for nonexistence.
+
+	* Version 3.54.6.
+
+	* read.c (read_makefile): Don't read off the end of the string after an
+	`include'.
+
+	* job.c (exec_command): New function to search the path for a file and
+	execute it.
+	(start_job): Use exec_command rather than execvp.
+
+	* read.c (read_makefile): Expand `include' directive args before
+	parsing them.  Allow trailing whitespace after filename.
+
+	* variable.c (target_environment): Put makelevel + 1, rather than
+	makelevel, in the `MAKELEVEL' envariable.
+
+Sat Jul 29 10:27:04 1989  Roland McGrath  (roland at hobbes.ai.mit.edu)
+
+	* remake.c (notice_finished_file): Don't get the new modtime of phony

+
+	* commands.c (start_job): Use fork instead of vfork, because a vfork
+	parent and child share file descriptors, and our child needs to diddle
+	with stdin.
+
+	* variable.c (initialize_file_variables): When created a new variable
+	set, zero out the hash table.
+
+	* variable.c (target_environment): Don't use variables whose names are

+
+	* variable.c (allocated_variable_expand): Now
+	allocated_variable_expand_for_file, calling variable_expand_for_file,

+
+	* commands.c (child_handler): Don't check C->command_ptr before calling

+	it's easier to let start_job handle all that.
+
+	* commands.c (struct child): New member `command_line', to hold an
+	index into file->cmds->command_lines.
+	(execute_file_commands): Set the new child's `command_line' to 0 and
+	its `commands' and `commands_ptr' to nil.
+	(start_job): When CHILD->command_ptr runs out, increment
+	CHILD->command_line and run the corresponding line from
+	CHILD->file->cmds->command_lines.  Run it even under -t, -q, or -n if
+	the CHILD->file->cmds->lines_recurse element for that line is set.
+
+	* commands.c (execute_file_commands): Chop CMDS up into lines, setting
+	its `command_lines' and `lines_recurse' members, if it wasn't already
+	chopped.
+
+	* commands.h (struct commands): New members `command_lines' and
+	`lines_recurse'.  The first is an array of chopped-up lines; the second

+	recursive.
+
+	* variable.c (variable_expand_for_file): If FILE is nil, just do a

+	To support this, take an additional argument FILE.
+
+	* variable.c (initialize_file_variables): New function to initialize
+	FILE's variable set list from PARENT's setlist.  PARENT is the
+	immediate dependent that caused FILE to be remade, or nil if FILE is a

+	should be passed as nil when defining per-file variables.)
+
+	* variable.c (variable_expand_for_file): New function to expand a line
+	using the variable set of a given file, and reporting error messages
+	for the file and line number of that file's commands.

+	set.
+
+	* commands.c (set_file_variables): New function to set up the automatic
+	variables for a file in its own variable set.
+	(execute_file_commands): Use set_file_variables.
+
+	* variable.c (new_environ): Replaced with target_environment, taking an
+	argument FILE, and returning an environment for FILE's commands.
+
+	* variable.c, variable.h: Remove all global special variable pointers.
+
+	* variable.c (define_variable_for_file): New function like
+	define_variable, but takes additional arg FILE, and defines the

+	variable sets.

+	* file.h (struct file): New member `variables', a `struct
+	variable_set_list' containing the list of variable sets used in the
+	expansion of the file's commands.
+
+	* variable.c (variables): Replaced with static `struct variable_set'

+	argument SET, the `struct variable_set' to look it up in.

+	`struct variable_set_list' using lookup_variable_in_set.

+	* variable.h (struct variable_set): New structure, containing a hash
+	table and the number of hash buckets.
+	(struct variable_set_list): New structure, containing a link for a
+	linked-list, and a `struct variable_set'.
+
+	* commands.c (start_job): Under -n, return what the recursive start_job
+	call returns, since it might actually start a child.
+
+	* make.texinfo (Rules: Wildcards): Document ~ and ~USER expansion.
+
+	* commands.c (execute_file_commands): If start_job returns
+	failure, but -t is set, set FILE->update_status to success.
+	(start_job): If -t is set, and the commands are not recursive, return
+	failure (is is done for -q).
+
+	* remake.c (touch_file): New function to touch FILE.
+	(remake_file): Use touch_file.  When touching a file, still do
+	execute_file_commands.
+
+	* remake.c (remake_file): Don't check question_flag (-q), since we
+	can't know here if the commands are recursive.
+
+	* commands.c (start_job): Don't use the `recursive' member of
+	CHILD->file->cmds.  Instead, check for leading +s and $(MAKE) or
+	${MAKE} in the command line here.
+
+	* commands.h (struct commands): Remove `recursive' member.
+
+	* rule.c (install_default_pattern_rules): Remove use of `recursive'

+	core dump.

+
+	* read.c (multi_glob): Use allocated_expand_variable for checking

+	`wildcard' function expansion.
+
+	* variable.h: Declare allocated_expand_variable.
+
+	* variable.c (allocated_expand_variable): New function to do variable
+	expansion in an allocated buffer, rather than the static one.

+
+	* glob.c (glob_tilde, glob_filename): Removed ~ expansion.
+
+	* variable.c (define_variable, lookup_variable): Use a smarter hashing

+	(VARIABLE_BUCKETS): Increased to 523.
+
+	* file.c (enter_file, lookup_file, rename_file): Use a smarter hashing

+	variable definitions containing newlines are done with `define'
+	directives.  Nonrecursive variable definitions containing newlines, and
+	variable names containing :, =, or newlines, will come out garbled.

+	quoting the %s.
+
+	* read.c (record_files): Pass new args to patsubst_expand.
+
+	* variable.c (patsubst_expand): Take two new args: PATTERN_PERCENT
+	and REPLACE_PERCENT.  Each of these, if non-nil, means that PATTERN
+	(or REPLACE) has already been run through find_percent, and
+	PATTERN_PERCENT (or REPLACE_PERCENT) is the result.
+
+	* make.h: Declare find_percent instead of pattern_p.
+
+	* read.c (pattern_p): Changed to find_percent, returning a pointer

+
+	* read.c (pattern_p): New function to search for an unquoted % in a

+	(record_files): Use pattern_p to check for implicit rules.
+	(read_makefile): Use pattern_p to check for static pattern rules.

+
+	* make.h, glob.c: If __GNUC__ is defined, use __builtin_alloca.

+
+	* Version 3.42.
+
+	* rule.c (default_variables): Set F77 to $(FC) and F77FLAGS to

+	the implicit rules, unless we trash FC and FFLAGS (which BSD uses).
+	[USG]: Set GET to `get' rather than `/usr/sccs/get'.

+	names together!  Reset HASHVAL before computing the second value.
+
+	* dir.c (check_changed_directories): Zero the new file hash table

+	directory exists.
+
+	* vpath.c (check_changed_vpaths): New function to run through the

+	returning.
+	make.h: Declare check_changed_directories.

+
+	* commands.c (child_handler): When the child of the `shell' function
+	completes, set `shell_function_completed' to 1 if it actually ran,

+
+	* version.c: Removed copyright notice, since this is a one-line file.
+
+	* commands.c (error_status): Made it return BUF, rather than running

+	ignoring it to avoid a race condition when child_handler is returning.

+	of child_handler).

+	Also support Modula-2 compilation (suffixes .sym, .def, and .mod).
+	Ratfor Yacc support is gone, since nobody has yacc -r.
+	All EFL support is gone, since nobody uses EFL.
+
+	* ar.c, arscan.c: Don't assume `long int' and `int' are the same.
+
+	* commands.c [USG]: Fixed wait status bit encoding.
+	[USG and not USGr3] (dup2): Define this for SysVr2.
+

+
+	* variable.c (variable_expand): When checking for `$($(foo))', use
+	lindex so as not to search for the second `$' outside the parens.
+
+	* make.c (struct stringlist, main, decode_switches): Changed `index'
+	member to `idx'.
+
+Sat Dec 24 16:02:32 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* commands.c (wait_for_children [USG]): Handle SIGCLD with SIG_DFL,
+	rather than SIG_IGN.  Ignoring SIGCLD reportedly makes wait return -1.
+
+	* arscan.c [USGr3]: Define PORTAR to 1 (as with sun386).
+	(ar_scan [USGr3]): Remove trailing slashes from member names.
+
+Thu Dec 22 17:54:05 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* make.texinfo (Makefiles: Overriding Makefiles): New node

+
+	* make.c (struct command_switch, command_switches, et al): New
+	member `noarg_value', if not nil, ptr to value to use if no arg is

+
+	* read.c (read_all_makefiles, read_makefile): Make makefiles precious.
+
+	* make.c (decode_switches): For a positive_int or floating option,

+
+	* make.c (decode_switches): If we got any unknown options, die after

+	start_job.
+
+	* commands.c (child_handler: USG): Record the pid wait returns.

+	name, set its contents equal to FILE's (ick).
+
+	* variable.c (define_automatic_variables): Pass all the args to
+	define_variable when defining MAKELEVEL!
+
+	* commands.c (execute_file_commands): If max_load_average > 0, and
+	we have children running, don't start up another child until the
+	load average goes below max_load_average.
+
+	* make.c: New variable `max_load_average'.
+	(struct command_switch, decode_switches, decode_env_switches):

+	right order.
+

+	in serial, and return as soon as one goal whose `changed' member is
+	nonzero  is successfully remade.
+
+	* commands.c: Don't include <sys/fcntl.h>.
+
+	* commands.c (construct_command_argv): Added ` to sh_chars.
+
+	* make.h: Don't declare construct_makeflags.
+
+	* make.c (main): Set up MAKEFLAGS and MFLAGS and make an environment
+	both before and after reading the makefiles, so the makefiles can
+	use them and possible change them, and later children will get the
+	right information.
+	(construct_makeflags): Replaced with define_makeflags (static void),
+	which defines the two variables.
+	* variable.c (define_automatic_variables): Don't define MAKEFLAGS
+	and MFLAGS.
+
+Mon Dec 12 14:40:31 1988  Roland McGrath  (mcgrath at helen.Berkeley.EDU)
+
+	* Version 3.27.
+
+	* commands.c (child_handler): Reset the handler to ourselves when
+	called for USG, since it has no safe signals.
+
+	* commands.c: For USG, use an int rather than a `union wait' for
+	wait calls, and dissect it with bitmasks.
+	(child_handler): No wait3 system call in USG.  Since we can't
+	protect from hanging, always return immediately if we have no
+	children we know about and we're not running a `shell' function.
+	(There is still the danger of hanging waiting for a child that died
+	without our being notified.)
+
+	* remake.c: Include <fcntl.h> instead of <sys/file.h>.  What we need
+	is really in <fcntl.h>, and while BSD <sys/file.h> includes
+	<fcntl.h>, USG doesn't.
+
+	* make.c (main): Figure out the program name before doing anything
+	which might need it (in a call to error or fatal).
+
+	* dir.c, glob.c: Use `struct dirent' and <dirent.h> for USGr3.
+
+	* arscan.c (ar_scan): Added missing & before buf (which is an int)

+
+	* Version 3.26.
+
+	* dir.c (find_directory, dir_file_exists_p): Keep track of how many
+	directories we have open and don't let it be more than
+	MAX_OPEN_DIRECTORIES (currently 10).
+
+	* variable.c (expand_function: `foreach'): Use expand_argument
+	rather than variable_expand so each repetition doesn't clobber the
+	last!!!
+
+Mon Dec  5 15:58:46 1988  Roland McGrath  (mcgrath at hecuba.Berkeley.EDU)
+
+	* Version 3.25.
+
+	* Makefile: Define `install' target.
+
+	* GNUmakefile: Don't include GNUmakefile or depend in the

+
+	* remake.c (check_dep): Set *MUST_MAKE_PTR nonzero if a dependency
+	doesn't exist.
+
+	* ar.c (ar_member_date, ar_touch): Make sure the modtime of the
+	archive file itself is known before we fetch or change the modtime
+	of one of its members.
+
+	* read.c (read_makefile): Expand variable and function references
+	before parsing rules so variable can contain special characters
+	(colons and semicolons).
+
+Sat Nov 26 11:36:31 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* variable.c (expand_function: `filter', `filter-out'): Fixed so
+	that filter-out works right.
+
+	* variable.c (expand_function: `filter', `filter-out'): Made these
+	functions use each word of their first argument as a pattern.
+
+Fri Nov 25 10:51:47 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.24.
+
+	* read.c (record_files): If a target is listed more than once in a
+	single rule (that defines commands), give a warning message rather
+	than the counter-intuitive message saying commands were already
+	defined (in the same place).
+
+	* make.c (fatal, error): Made them both take 6 args since there is
+	at least one error message that need that many.  Too bad vfprintf is
+	not universal!
+
+	* Version 3.23.
+
+	* read.c (read_makefile): Moved the construction of the `struct
+	commands' into record_files.  Call record_files before recursing for an
+	included makefile so the higher-up will determine the default goal.
+	(record_files): Take arguments COMMANDS, COMMANDS_IDX and
+	COMMANDS_STARTED and construct a `struct commands.
+
+Thu Nov 24 14:36:33 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* Version 3.22.
+
+	* make.c (main): Made it a fatal error if we can't move back to the
+	directory we started in before re-execing.
+
+	* make.c (main): Get the current directory before doing anything
+	else, so we know it even if we don't need it for the value of
+	`MAKE', since we might want it when re-execing.
+
+Wed Nov 23 13:34:44 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+
+	* Version 3.21.
+
+	* read.c (record_files): Eliminate duplicate deps in a chain.
+
+	* variable.c (expand_function: `sort'): Pass the right number to
+	qsort, not one less.
+
+	* remake.c (remake_file): Always call notice_finished_file if
+	FILE->command_state == cs_finished.
+
+	* commands.c (execute_file_commands): Call notice_finished_file to
+	set FILE's status correctly when start_job fails (because it's out
+	of commands or running under -n).
+
+Fri Nov 18 15:31:12 1988  Roland McGrath  (mcgrath at saffron.Berkeley.EDU)
+
+	* Version 3.20.
+
+	* remake.c (update_file_1): Set the `update_status' of FILE to
+	nonzero and set FILE's `updated' bit if we have decided to give up
+	on remaking FILE because of errors in the dependencies.
+
+	* rule.c (pattern_search): Debugging messages use `dependency' (vs.
+	`dependent') properly.
+
+	* make.texinfo (Conditionals: Conditional Syntax): Function index
+	entries for `ifndef' and `ifneq'.
+
+	* variable.c (define_automatic_variables): Define `MAKELEVEL' to the

+	* remake.c (remake_file): Call notice_finished_file after touching.

+
+Fri Nov 11 08:02:26 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (fatal, error): Made error messages for recursive runs be
+	shorter.
+
+Thu Nov 10 16:51:36 1988  Roland McGrath  (mcgrath at basil.Berkeley.EDU)
+
+	* Version 3.18.
+
+	* read.c (read_makefile): Made it eat leading spaces and formfeeds
+	(but not tabs), like it's documented to.
+
+	* read.c (read_makefile): Let included makefiles determine the
+	default goal, as is done by System V Make.
+
+Tue Nov  1 19:03:08 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* variable.c (new_environ): Don't increment VCNT when a variable is
+	rejected.
+
+Fri Oct 28 16:54:15 1988  Roland McGrath  (mcgrath at basil.Berkeley.EDU)
+
+	* Version 3.17.
+
+	* rule.c (convert_to_pattern): Don't use the same storage for a name
+	in two rules since new_pattern_rule may free this storage when a
+	rule is discarded.
+
+	* rule.c (new_pattern_rule): Undid useless change I made Oct 25.
+
+Thu Oct 27 19:17:53 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* Version 3.16.
+
+	* GNUmakefile, Makefile: Fixed a typo in a comment.
+	* Makefile: Removed malloc.o from object file list.
+
+	* variable.c: Removed old debugging #define's for xmalloc and
+	xrealloc so non-ANSI cpp's won't barf.
+
+	* make.c (main): Made local array for temp file name static so
+	compilers that don't do auto aggregate initialization won't barf.
+
+	* read.c: Removed static declaration of copy_dep_chain since it is
+	no longer static.
+
+Tue Oct 25 16:59:30 1988  Roland McGrath  (mcgrath at pepper.Berkeley.EDU)
+
+	* rule.c (new_pattern_rule): If we threw out the new rule because it
+	matched an old one and OVERRIDE was zero, don't put the freed
+	pointer in the chain!
+

+
+	* Version 3.15.
+
+	* variable.c (expand_function: `sort'): Don't do the sorting and
+	writing out if there were no words in the first place.
+
+	* remake.c (remake_file): Only fail with a "no way to make" message

+	non-target file we don't know how to remake.
+

+	a file whose `is_target' flag is not set.
+
+Tue Oct 18 17:24:11 1988  Roland McGrath  (mcgrath at paris.Berkeley.EDU)
+
+	* variable.c (expand_function: `patsubst', `subst'): Free the right
+	things!
+
+	* variable.c (expand_function: `subst'): Don't clobber the
+	pointer to the end of the second arg and then try to use it!!!
+
+Mon Oct 17 16:44:45 1988  Roland McGrath  (mcgrath at catnip.Berkeley.EDU)
+
+	* variable.c (expand_function: `patsubst'): Don't clobber the

+	so that it really works, now that parens are counted.
+
+	* remake.c (update_file_1): Set FILE's `updated' flag after calling
+	remake_file if it failed or finished immediately.
+
+	* remake.c (update_file): Use the `updated' flag rather than the
+	command state to decide if a file was fully considered, and
+	therefore might give an "up to date" message.
+
+	* variable.c (expand_function): Made all functions that take more
+	than one argument count parens of the appropriate flavor in their
+	args and ignore commands nested in parens.
+

+
+	* GNUmakefile: Added an explicit rule for make.dvi since the
+	built-in .texinfo.dvi implicit rule is screwed up.
+
+	* rule.c (default_suffix_rules): Added a comment that the
+	.texinfo.dvi rule does not work because of an ahem, feature of Make
+	that at some point will be fixed--er, enhanced to alleviate this
+	difficulty.
+
+	* rule.c (default_suffix_rules): Fixed Texinfo -> DVI rule (again).
+
+	* make.texinfo (Commands: Execution): Documented new competing for
+	standard input among children.

+	child has the stdin that doesn't point into nirvana.
+	(good_stdin_used): New variable to tell if any child has the good
+	standard input.
+	(child_handler): Reset `good_stdin_used' if a dead child's
+	`good_stdin' flag is set.

+
+	* read.c (read_makefile): Reset `reading_filename' and
+	`reading_lineno_ptr' after recursing for an included makefile.
+
+	* GNUmakefile: New GNU Make-specific makefile that does everything
+	Makefile does plus distribution stuff, and doesn't contain any hacks
+	to try to work with Unix make.
+
+	* Makefile: Removed distribution stuff.
+
+	* make.c (main): Use mktemp to construct the names of temporary
+	files used for standard input makefiles.
+
+	* make.c (main): Don't turn standard input into a broken pipe.
+
+	* commands.c (start_job): Keep two extra file descriptors around: a
+	good standard input, and a bad one that reads from a broken pipe.
+	On the child side of the fork, if there are other children, give
+	this one the broken pipe so they won't compete; if this is the only
+	one, give it the good standard input.
+
+	* make.h: Declare notice_finished_file.

+	running, rather than diddling with `job_slots'.
+	(execute_file_commands): Increment `job_slots_used' before calling
+	start_job and decrement it on failure to avoid race condition.
+	If there is only one job slot, wait for the child to finish and
+	return its status so commands are run in linear order, as if there
+	were no parallelism.

+
+	* make.c (main): Put a ".PHONY: /tmp/foo" line in front of temp

+	* remake.c (update_goal_chain): Judge files as being finished based
+	on their `updated' flag, not their state.
+
+	* read.c (read_makefile): Don't check for FILENAME being "-".

+	was also given on the command-line.
+
+	* read.c (read_makefile): Enter the `struct file's for the makefiles
+	added to the `read_makefiles' `struct dep' chain.
+
+	* remake.c (update_goal_chain): Made it not enter the files for the

+
+Fri Sep 30 18:56:20 1988  Roland McGrath  (mcgrath at nutmeg.Berkeley.EDU)

+	chain of all makefiles read.
+	(read_makefile): Now takes two args: FILENAME and TYPE, which is 0
+	for a normal makefile, 1 for MAKEFILES variable or 2 for an included
+	makefile.  Add a `struct dep' containing the name of the makefile
+	(as it was found in the search path for type 2s), and TYPE in the
+	`changed' member to the global `read_makefiles' chain.
+
+	* make.h, rule.c (displace_pattern_rules,
+	add_displaced_pattern_rules): Removed these functions.
+
+	* read.c (read_makefile): Variable-expand the name of an `include'd
+	makefile before calling find_makefile on it.
+
+	* file.c (snap_deps): If the `struct file' for a `struct dep'

+	use correct length of "MFLAGS" (6, not 5).
+
+	* read.c (read_makefile): Don't stop reading when readline returns

+	command state to `cs_finished'.
+
+	* remake.c (update_file): Don't write the "up to date" message if
+	update_file_1 returned a nonzero status.
+
+Wed Sep 28 16:30:07 1988  Roland McGrath  (mcgrath at catnip.Berkeley.EDU)
+
+	* commands.c (child_handler): Set the `update_status' member

+	put in the the new `struct child's `environ' member.
+	(child_handler): When freeing a child, free its `commands' member, the
+	elements of its `environ' array and its `environ' member itself.
+	(start_job): Set `environ' to the child's `environ' member before
+	exec'ing the command.
+
+	* variable.h, variable.c (new_environ): Made it return the new
+	environment, not putting it in `environ'.
+
+	* remake.c (update_file): Don't give a "is up to date" message
+	unless no files were remade and the state went from `cs_not_started'
+	to `cs_finished', so repeat calls to finish jobs won't get the message.

+
+	* make.c (main): Use wait_for_children rather than child_handler.
+
+	* commands.c (wait_for_children): New function to block waiting for
+	children, insuring that child_handler is not called recursively.

+
+	* commands.c (child_handler): Start up additional commands in a
+	sequence after an ignored error.
+
+	* remake.c (update_file): Don't print "`foo' is up to date" messages
+	when update_file_1 returns while commands are executing.
+

+	the bloody `struct file', dammit!!
+
+	* commands.c (child_handler): Print out the "*** ..." error message
+	when not under -i.  (I somehow forgot this.)
+
+	* remake.c (update_file_1): Use name_mtime rather than file_mtime to
+	re-get the mtime of a file whose commands have finished.
+
+	* make.c (command_switches, decode_switches, decode_env_switches):
+	Make all switches that take string args allow them right after the
+	switch letter.
+
+	* commands.c (child_handler): Check for a child being the `shell'
+	function's command returning and set the global variable for
+	expand_function to check.
+
+	* variable.c (expand_function): For the `shell' function, instead of
+	waiting for the child shell ourselves, let child_handler do it and

+
+	* remake.c (update_file_1): If deps are running, set state to

+
+	* remake.c (update_file_1): Don't return if FILE's state is

+	corresponding file's `update_status' and `updated' flags as
+	appropriate, and reset the modtimes of the file and any `also_make'
+	files it has.
+
+	* remake.c (remake_file): Don't re-set `last_mtime' and set `updated'.
+
+	* commands.c (fatal_error_signal): Don't swallow all the children

+	(construct_makeflags, decode_switches, decode_env_switches):
+	Handle`positive_int'-type switches.
+
+	* glob.c (glob_vector): Rename local variable `vector' to `VeCtOr'.
+	This is said to avoid a conflict with some system's global `vector'
+	variable.
+
+	* variable.c (expand_function): Made the `shell' function use
+	construct_command_argv and do its own child control and piping.
+
+	* make.c (main): Turn standard input into a broken pipe after

+
+	* commands.c (struct child): Remove `pipe_fd' member.  We don't use
+	pipes any more.
+	(start_job): Return 0 for success, 1 or failure (rather than void).

+	`noerror' members to keep track of info about a command thread.
+	(start_job): New function to start a job and update the argument
+	`struct child' to reflect its status.

+	Made it use new start_job function.
+
+	* rule.c (freerule): Don't free the `struct commands' of the
+	discarded rule.  It may be used in more than one place.
+
+	* commands.c (execute_command_line): Made it not try to delete the
+	possibly partly-made file.  The child_handler function will do this.
+	(fatal_error_signal): Ditto + call kill_children.
+
+	* make.h: Declare job_slots.
+
+	* make.c (main): Collect goals in a dep chain and run through this
+	chain waiting for a child, eliminating finished goals, updating all
+	remaining goals, and quitting if they fail and not -k.
+
+	* commands.c (child_handler): If called with SIG < 0, - SIG is the
+	max number of children to bury.
+
+	* commands.c (child_handler): If called with SIG as zero,
+	block waiting for running children.
+	(kill_children): Call child_handler with zero rather than SIGCHLD.
+
+	* remake.c (update_file_1): Use the `command_state' member of FILE
+	and its dependencies to determine what commands are running, what to

+	time we were called, return their status.
+
+	* commands.h: Declare kill_children.
+
+	* commands.c: Define `struct child' to keep track of child
+	processes, with the chain in `children'.
+	(child_handler): New function to catch child-termination signals
+	(SIGCHLD, or SIGCLD for USG), store the returned status in the
+	appropriate structure, take the now-obsolete `struct child' out of
+	the chain, and free its storage.
+	(execute_file_commands): Put all of the stuff invloving running the
+	commands into new function run_file_commands.  Execute_file_commands
+	now does process management for the commands, while
+	run_file_commands (which is run in a subprocess) runs the commands.
+	(kill_children): New function to kill all running children by
+	sending them signal SIG.  If there are any children still living
+	after they are all sent SIG, they are all sent SIGKILL.
+
+	* make.c (main): Catch SIGCHLD (SIGCLD for USG) with child_handler.
+
+	* commands.h: Declare child_handler function.
+
+	* commands.c (execute_file_commands): Check the `command_state'

+
+	* read.c (read_all_makefiles): Install the default pattern rules

+
+	* Makefile: Put tags files in the tarfile.

+	was a command-line target.
+
+	* make.c (main): Enter command-line targets as files and set their
+	`cmd_target' members.
+
+	* file.h (struct file): Added `cmd_target' member.
+
+	* read.c (read_makefile): Temporarily turn off -t and -q while
+	updating makefiles.
+
+	* make.c (main): Don't use arg 0 from other_args (which is now
+	argv[0]; i.e., the program's name).
+
+	* read.c (read_makefile): Only return nonzero if commands were
+	actually run to remake the makefile.
+
+	* remake.c (update_file_1): Set FILE->updated to -1 if no commands
+	were actually run (because no update was done or -t was given).
+
+	* make.c (decode_switches): Fixed bug wherein xrealloc was passed
+	bad args if it tried to expand other_args->list.
+
+	* read.c (read_all_makefiles): Made it not look at the `MAKE'
+	variable, just use argv[0].
+

+
+	* read.c (rerun_make): New function to re-exec make.
+
+	* make.c (construct_makeflags, construct_argv): New functions to

+	(read_all_makefiles): Pass a nonzero UPDATEIT arg to read_makefile
+	for all default and -f makefiles and all makefiles from the
+	`MAKEFILES' variable.  If any of the makefiles has changed, re-exec

+
+	* remake.c (update_file): Print a "File `foo' up to date'" message
+	under -p.
+
+	* commands.c (execute_file_commands): Allocate one byte for each of

+
+	* read.c (record_files): Made it not free the storage for the name
+	if it started with `./' and was therefore not quite the same as in
+	the `struct file'.
+
+	* read.c (record_files): If commands were specified twice, the error
+	message specifies in what files and at what line numbers.
+
+	* make.c (main): If any of the signals we usually fatal on were
+	ignored by the parent (probably a shell), ignore them.
+
+	* make.c (main): Print version info for -v, -p, or -d.

+
+	* file.c: Increased number of hash buckets to 1007.
+
+	* rule.c (count_implicit_rule_limits): Moved comptation of

+	`maxsuffix', and must be called before count_implicit_rule_limits.
+
+	* rule.c (pattern_search): If an existent (non-intermediate)
+	dependendency was found via a terminal rule, set its
+	`tried_implicit' flag, so it will never have implicit rule search done.

+
+	* make.texinfo: Documented `shell' function.

+
+	* remake.c (update_file_1): Made it not just return before executing

+
+	* rule.c (default_pattern_rules, default_variables): Made it use
+	`$(AR)' for `ar r' (to put files in archives).
+
+	* vpath.c (build_vpath_lists): Made it recursively expand the
+	`VPATH' variable (by using variable_expand instead of lookup_variable).
+
+	* read.c (conditional_line): Made it not swallow whitespace after
+	the comma in an `ifeq' using the `(a,b)' syntax.
+
+	* rule.c (count_implicit_rule_limits): Made it not crash if a

+
+Sun Aug 28 15:51:12 1988  Roland McGrath  (mcgrath at homer.Berkeley.EDU)
+

+
+	* make.texinfo: Clarified that both -Idir and -I dir are allowed.
+
+Sat Aug 27 13:49:28 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)

+
+	* make.c (collapse_continuations): Bug fix from RMS.
+
+	* rule.c (install_default_pattern_rules): Made it set the
+	`in_use' flag of the created rules to zero, rather than letting
+	it be random garbage.
+
+	* rule.c (pattern_search): Fixed putting `also make' targets into
+	file strucutres.
+
+	* read.c (record_files): Fixed bug which made double-colon entries
+	make it read off into space.
+
+	* make.c (decode_switches): Made it understand `ignored' switches
+	rather than dumping core.

+
+	* read.c (read_makefile): Made it accept ^L's as whitespace.
+	* make.c (next_token, end_of_token): Ditto.

+	directive) matched the filename.
+
+Sat Aug 13 14:20:46 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (decode_switches, main): Made the command switches be

+
+	* make.texinfo: Minor editorial changes.
+
+	* read.c (read_makefile): Minor speed improvement by freeing and

+	unnecessary bcopy.
+
+Thu Aug 11 00:10:43 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.texinfo: Fixed some unquoted @'s.

+
+	* variable.c (print_variable_data_base): Fixed bug which made -p
+	dump core.  (This was a really idiotic bug.)
+
+	* rule.c (pattern_search): Fixed a bug which made it make the
+	`also_make' member of the file in question nil if the first of
+	the successful rule's targets was the matching one.
+	Made it use only as much storage as necessary in the `also_make'
+	member.
+	(create_pattern): Made it use only as much storage as necessary in
+	the `lens' and `suffixes' members of the created rule.
+
+	* remake.c (library_file_mtime): Made it `static'.
+
+	* file.c: Added a declaration for `errno', which is declared in some
+	<errno.h>'s, but not all.
+
+	* file.h (struct file): Added `also_make' member for multiple-target
+	implicit rules.
+	* rule.c (pattern_search): Made it put the names of files updated by
+	the given file's commands in its `also_make' member.
+	* remake.c (update_file_1): Made it mark the files in a file's
+	`also_make' member as updated when the file is updated.

+	define a variable with the name of the whole definition when there
+	was no space before the = or :=.
+
+	* make.texinfo (Features): Made the changes which were made in RCS
+	revision 2.7 but somehow lost since then.  Added -W.
+
+Tue Aug  9 10:04:50 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* variable.h: Added `o_default' to `enum variable_origin'.
+	* variable.c (print_variable_data_base): Made it print the origins of
+	the variables.
+	* rule.c (install_default_pattern_rules): Made it define the default
+	variables with origin `o_default'.
+
+	* make.texinfo: Documented -W.
+
+	* make.c (decode_switches, main): Added the -W flag to give files a
+	time-stamp of now, for a `what if' effect when used with -n.

+	* commands.c (print_commands): Made it say `(built-in)' for commands
+	that are built into the default ruleset.
+
+	* read.c (record_file): Made .SUFFIXES get its deps frontwards (again).
+	* rule.c (set_default_suffixes, convert_to_pattern): Made it read
+	.SUFFIXES's deps frontwards, so the converted rules will not be in
+	reverse order.
+
+	* rule.c (new_pattern_rule): Fixed a bug wherein it would keep
+	searching after it had removed a matching rule and ended up diddling
+	with freed storage.
+
+	* rule.c (freerule): Made it take the given rule off the chain.
+	(new_pattern_rule, count_implicit_rule_limits): Use freerule to
+	remove rules from the chain.
+
+	* vpath.c (construct_vpath_list): Made it return after cleaning out
+	all previous searchpaths when given a nil DIRPATH arg, so it won't
+	go into the construction code and dump core dereferencing a nil
+	pointer.
+
+	* variable.c (patsubst_expand): Fixed a bug which made it not match
+	correctly and sometimes dump core.
+
+Mon Aug  8 16:35:48 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (default_suffix_rules): Made the .texinfo.dvi rule remove
+	the files used in the comparison to determine whether or not a
+	second TeX run is necessary.
+
+	* make.texinfo: Fixed some overfull TeX hboxes.
+
+	* make.texinfo (Implicit: Catalogue of Rules): Fixed a Texinfo error.
+
+	* rule.c (create_pattern_rule): Fixed bug wherein index was not
+	being passed its second arg.
+
+	* read.c (getline): Merged back into readline.
+
+	* rule.c (default_suffixes, default_suffix_rules,

+	.texinfo.dvi and .texinfo.info rules.
+
+	* make.texinfo (Top): Changed `last updated' date to be correct (for
+	the last time it was updated, not today).  Changed `for version
+	3.00' since it's not going to be called that.
+
+Sat Aug  6 19:51:10 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* commands.c (print_commands): Added this function to print the
+	contents of a `struct commands' for -p.
+	* rule.c (print_rule_data_base): Use above.
+	* file.c (print_file_data_base): Ditto.
+
+	* rule.c (count_implicit_rule_limits, new_pattern_rule,
+	install_pattern_rule, print_rule_data_base): Made it understand the
+	changed `struct rule' and act accordingly.
+	(freerule): Added this function to free all the storage used by a rule.
+
+	* rule.c (pattern_search): Made it grok multiple targets of pattern
+	rules.  The matching is done properly, but at present, only the
+	matching pattern's target is used to give deps and commands.
+
+Fri Aug  5 18:00:29 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (struct rule): Changed name, namelen, and patsuffix members
+	to targets, lens, and suffixes, which are arrays, for multiple targets.
+	(create_pattern_rule): Now takes first arg TARGETS, a nil-terminated
+	array of targets, rather than a single target and patsuffix pointer.
+
+	* read.c (record_files): If it finds an implicit pattern rule, it
+	collects all the targets into an array and passes the whole thing to
+	create_pattern_rule.  If there are non-pattern targets, it is a
+	fatal error.
+
+Tue Aug  2 15:06:38 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (readline): Split backslash-newline checking from reading
+	and buffer-expanding.
+	(getline): Created to do the reading and buffer-expanding formerly
+	done in readline.
+
+	* rule.c (pattern_search): Made it reject nonterminal match-anything
+	rules when a specific rule has matched, rather than rejecting
+	terminal match-anything rules in this case.
+
+	* rule.c (convert_to_pattern): Fixed a bug caused when the change to
+	make it only recognize two-suffix rules whose target suffixes
+	precede their dependency suffixes which made it work in the opposite
+	direction (even worse than it started out).
+
+	* rule.c (pattern_search): Made it reject nonterminal match-anything
+	rules as intermediate targets when searching for both real and
+	intermediate dependencies, rather than only when searching for
+	intermediate ones.
+
+Sun Jul 31 00:33:56 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (convert_to_pattern): Made it only recognize two-suffix
+	rules whose target suffix comes before the dependency suffix in the
+	.SUFFIXES list.
+
+	* variable.c (define_automatic_variables): Made all automatic
+	variables be defined with origin `o_automatic'.
+
+	* variable.h: Added `o_automatic' to `enum variable_origin'
+
+	* file.c (remove_intermediates): Made it not print an error message
+	if the error was that the file does not exist.
+
+	* rule.c: Removed `recursive' member from `struct rule'.
+
+	* remake.c (library_file_mtime): Made it not use the directory hash
+	functions, as reading in and hashing /usr/lib and /lib is slow and
+	most likely unnecessary.
+
+	* remake.c (remake_file): Changed message from ``No specification
+	for making'' to ``No way to make'' so it will be short enough that
+	most filenames will fit on a line.
+	Made it look at the `recursive' member of the `struct commands',
+	rather than of the `struct file' (which no longer has one).
+
+	* commands.c (execute_file_commands): Made it look at the
+	`recursive' member of the `struct commands', rather than of the
+	`struct file' (which no longer has one).
+
+	* file.h: Removed `recursive' member from `struct file'.
+
+	* commands.h: Added `recursive' member to `struct commands'.
+
+	* dep.h: Removed unused `quotedparen' member from `struct nameseq'
+	and `struct dep'.
+
+	* read.c (dequote): Removed this function.
+	(multi_glob): Removed reference to `quotedparen' member of
+	a `struct nameseq' and calls to dequote.
+
+	* read.c (record_files): Made it set the stem for $* for all static
+	pattern rules, not just those with commands given at that time.
+	Removed check for recursive commands.
+	Made it check for pairs of .SUFFIXES dependencies to reject as
+	default goals as well as single ones (that don't start with dots).
+	(read_makefile): Added checks for recursive commands to set
+	the `recursive' flag in the `struct commands'.
+
+Sat Jul 30 15:47:23 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* make.c (find_next_token): Made the LENGTHPTR arg optionally nil.
+
+	* make.c: Removed `files_made' variable which is defined static in
+	remake.c and used only there.
+	(main): Cleaned up somewhat.
+	(decode_switches): Cleaned up a bit.  Made an unknown option be a
+	non-fatal error.
+	(decode_env_switches): Made LEN arg unsigned.  Cleaned up.
+	(print_version): Made it say ``see the source'' rather than ``see
+	the source file'', since there is more than one.
+
+	* file.h: Made `num_intermediates' declared unsigned.
+
+	* file.c: Made `num_intermediates' variable unsigned.
+	(remove_intermediates): Removed unused FORMAT arg.
+	(enter_file): Made it handle double-colon files properly, adding the
+	new entry as the old entry's prev pointer.
+
+	* dir.c: Re-indented the `struct dir' definition to be right.
+	(dir_load): Cleaned up slighty.
+	(file_exists_p): Removed comment saying we could use `access', since
+	that is a bad idea (except for setuid programs).  Cleaned up slightly.
+
+	* commands.c: Changed some comments slightly.
+	(execute_file_commands): Cleaned up a bit.  Changed some comments,
+	added others.  Moved freeing of storage for $^ and $? to the same
+	place as for the other automatic variables.
+	(execute_command_line): Made `#' trigger a shell.
+	Added some comments.  Cleaned up a bit.  Put all the special chars
+	that trigger shells into an array easily changeable at the top.
+
+	* ar.c: Added comments explaining each function.
+	(ar_scan_1): Merged into ar_member_date.
+	(ar_member_date): Changed call to ar_scan_1 to the body of that
+	function.
+	(ar_member_date_1): Simplified to a ?: expression rather than an
+	if-else statement.
+	(ar_member_touch): Changed error handling around a bit.
+	None of these errors are fatal now.
+
+	* variable.c (subst_expand): Added a new arg BY_WORD, to do substs
+	only on full words.
+	(patsubst_expand): Fixed bug which made calls whose patterns
+	contained no `%' to not work correctly, by using above.
+	(variable_expand): Pass extra arg to `subst_expand'.
+
+	* variable.c (expand_function): Fixed bug which made `foreach' calls
+	with one-word lists run off into never-never land.
+
+Fri Jul 29 20:12:36 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* variable.c (expand_function): Made a very minor speed improvement
+	by avoiding an unnecessary strlen call.
+
+Wed Jul 27 16:01:47 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* rule.c (default_suffixes): Rearranged the list somewhat; added
+	`.el' and `.elc' to speed things up (especially when building
+	Emacs), for the same reason `.h' is there.
+
+	* read.c (record_files): Changed `lineno' from `long' to
+	`unsigned int'.
+
+Sun Jul 24 02:15:30 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* variable.c (expand_function): Eliminated use of `wstok'
+	because it is non-reentrant and unreliable.
+	Fixed a minor bug which would cause something not to be freed.
+	* make.c (wstok): Removed `wstok' because it is no longer used.
+
+	* variable.c (expand_function): Made `foreach' function put
+	spaces between output texts like it's supposed to.
+

+	* rule.c (install_pattern_rule): Fixed a bug which caused the
+	terminal and recursive flags to always be zero for rules
+	entered by this function.
+
+	* make.texinfo (Rules: Double-colon): Added a paragraph
+	explaining the purpose of double-colon rules.
+
+	* make.texinfo (Implicit: Catalogue of Rules): Updated to
+	reflect new C++, TeX, Web, and Texinfo rules.  Other slight
+	editorial changes.
+
+	* commands.c (execute_file_commands): Fixed a bug wherein
+	random memory could get written for files with no deps.
+	
+Wed Jul 20 19:30:31 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* read.c (readline): Fix bug wherein it would not recognize a
+	backslash-newline if the buffer filled up and was enlarged
+	right before reading the newline.
+	
+Tue Jul 19 19:55:02 1988  Roland McGrath  (mcgrath at chilli.Berkeley.EDU)
+
+	* read.c: Added default suffix rules for .cc (using $(C++),
+	which defaults to `g++', and $(C++FLAGS)), .tex, .dvi, .web
+	and .cweb (using $(TEX), $(WEAVE), $(TANGLE), $(CWEAVE) and
+	$(CTANGLE)).
+	
+Sat Jul 16 21:24:28 1988  Roland McGrath  (mcgrath at tully.Berkeley.EDU)
+
+	* Made error formats use %u rather than %ld for line numbers,
+	which are now unsigned int's rather than long's.
+
+	* read.c (conditional_line): Fixed some bugs caused by use of
+	unsigned int rather than int in one place.
+
+	* read.c (conditional_line): Put the info about active
+	conditionals in a struct.
+	(read_makefile): Make a new struct of info about conditionals
+	for included makefiles and restore the old one after the
+	included makefile has been read.
+
+	* read.c (read_makefile): Don't try to read a makefile with
+	name "" after giving an error message because an `include'
+	directive gave no filename.
+
+	* read.c (read_makefile): Give an error message for
+	non-whitespace text after the filename in an `include' directive.
+
+	* make.c (error): Take five args, like `fatal'.  It managed to
+	lose with only two.  Is there a better way to do this without vfprintf?
+
+	* read.c (read_makefile): Commands consisting of only
+	whitespace are not the same as no commands.  I thought I'd
+	fixed this bug months ago; it seems to have come back.
+
+	* make.c (collapse_continuations): All whitespace around a
+	backslash-newline combination is turned into a single space.
+
+	* Added COPYING file and copyright notices to all files.
+
+	* make.texinfo (Running: Goals): Fix a typo.
+
+	* read.c (do_define): Take an arg for the origin of the
+	variable being defined.
+	(read_makefile): Grok `override define'.
+
+	* make.texinfo (Variables: Override Directive, Defining):
+	Document the `override define' combination directive.
+
+	* ar.c (ar_member_date): Make a 0 return from `ar_scan' return
+	(time_t) -1 (nonexistent file), rather than (time_t) 0, which,
+	when put in the `struct file', makes `file_mtime' try to get
+	the mtime over and over again.
+
+	* variable.c (pattern_matches): Fix a bug that made patterns
+	not beginning with `%' never match.
