+ * Version 3.59.1.
+
+Fri Jan 10 03:48:08 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.
+ (child_handler): #ifdef on WAIT_NOHANG, not HAVE_SYS_WAIT || !USG.
+ Use WAIT_NOHANG macro instead of wait3.
+
+ * file.h (struct file.command_state): Remove unused elt.
+
+Wed Dec 26 18:10:26 1990 Roland McGrath (roland at albert.ai.mit.edu)
+
+ * commands.c (set_file_variables): If FILE got its commands from

+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
+ directory doesn't exist (but a rule might make it).
+
+ * make.h [__GNUC__]: Don't #define alloca if already #define'd.
+
+ * rule.c (convert_to_pattern): Don't look at the target constructed for
+ the empty rule when making the null-suffix rule. Construct it over
+ again, since the former may have been freed already.
+
+Thu Dec 13 17:21:03 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * make.h [__GNU_LIBRARY__]: Include <unistd.h> to get random fn decls.
+
+Wed Dec 12 17:12:59 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * make.h, arscan.c, glob.c: Only include <memory.h> #ifdef USG.
+
+ * variable.c (define_variable_in_set): Replace env_overrides check that
+ wasn't really redundant (undoing Sep 28 change). Add comment saying
+ why this check is necessary.
+
+ * job.c, main.c [DGUX]: Needs siglist like USG.
+
+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.
+
+ * read.c (find_percent): Do backslash folding correctly, not leaving

+
+Thu Dec 7 21:20:01 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * 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.
+ * commands.c (delete_child_targets), job.c (search_path), read.c
+ (construct_include_path): Use S_ISfoo(m) instead of
+ (m & S_IFMT) == S_IFfoo.
+ * dir.c, glob.c [_POSIX_SOURCE]: Use dirent.
+
+Wed Nov 29 22:53:32 1990 Roland McGrath (roland at geech.ai.mit.edu)
+
+ * Version 3.59.
+
+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.

+ * GNUmakefile: make-*.tar.Z: Include texinfo.tex.
+
+Tue Oct 23 19:34:33 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * main.c (define_makeflags): When there are no flags to write, make
+ sure the array has two leading nulls, since `MAKEFLAGS' is defined from
+ &flags[1].
+
+ * main.c (default_keep_going_flag): New variable (constant one).
+ (command_switches: -k, -S): Use above for default value.
+ (define_makeflags): Only write flag/flag_off switches if they are on,

+
+Mon Oct 22 16:14:44 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * main.c (struct command_switch): New member `no_makefile'.

+ (main): Call define_makeflags with MAKEFILE==1 before remaking
+ makefiles, and again with MAKEFILE==0 before remaking goals.
+
+Tue Oct 2 17:16:45 1990 Roland McGrath (roland at geech.ai.mit.edu)

+
+Mon Oct 1 15:43:23 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * arscan.c [HPUX]: Use PORTAR==1 format.
+
+Sat Sep 29 16:38:05 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * make.h, remake.c, arscan.c: Don't declare `open'.
+
+Fri Sep 28 04:46:23 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * variable.c (define_variable_in_set): Remove redundant -e check.
+
+Wed Sep 26 00:28:59 1990 Roland McGrath (roland at geech.ai.mit.edu)
+

+ CHILD->file->cmds->lines_recurse.
+
+ * commands.c (chop_commands): Don't botch the line count for allocating
+ CMDS->lines_recurse.
+
+ * Version 3.58.11.
+
+ * job.c (start_job): Don't always increment CHILD->command_line! Only
+ do it when CHILD->command_ptr has run out! (Dumb bug. Sigh.)
+
+Thu Sep 20 02:18:51 1990 Roland McGrath (roland at geech.ai.mit.edu)
+
+ * GNUmakefile [ARCH]: Give explicit rule for remote.{c,dep} to use
+ variable `REMOTE' for more flags.
+ ($(prog)): Link in $(LOADLIBES).
+
+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,
+ which is no longer necessary since we have cleverly avoided the issue.
+
+ * 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.
+ (variables_expanding): New variable, the chain of variables currently
+ 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.
+ * make.h: Put it here instead.
+
+ * variable.c (target_environment): If `.NOEXPORT' was specified as a
+ target, only export command-line and environment variables, and
+ file-origin variables that were in the original environment.
+
+ * make.man: Add missing ?roff control for `-I' option description.
+
+Thu Sep 13 14:10:02 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * load.c [UMAX]: Move #include <sys/sysdefs.h> to [not UMAX_43].
+
+Wed Sep 12 15:10:15 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * expand.c (recursively_expand): Don't use `reading_filename' and
+ `reading_lineno_ptr' if they're nil.
+
+Thu Aug 30 17:32:50 1990 Roland McGrath (roland at geech)
+
+ * Version 3.58.10.
+
+Tue Aug 28 04:06:29 1990 Roland McGrath (roland at churchy.ai.mit.edu)
+
+ * job.c [USG] (unknown_children_possible): New variable, set nonzero
+ when it's possible for children not in the `children' chain to die.
+ (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.
+
+ * job.c (exec_command): Don't take PATH and SHELL args. Get them from
+ ENVP.
+ (child_execute_job): Don't take FILE arg, and don't pass path and shell
+ to exec_command.
+ (start_job): Don't pass FILE arg to child_execute_job.
+ * 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
+ push_signals_blocked_p (0).
+
+ * main.c (fatal_signal_mask): New variable, mask of signals caught with
+ 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):
+ Renamed from children to signals. Use {block,unblock}_signals instead
+ of {block,unblock}_children.
+ * 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.
+
+ * file.c (print_file_data_base): Fix computation of avg files/bucket.
+
+Tue Jul 31 22:11:14 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * Version 3.58.7.
+
+Wed Jul 25 16:32:38 1990 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * arscan.c (ar_name_equal): Fixed to really do it right.
+ (ar_member_pos): Fixed order of args.
+ * ar.c (ar_member_date_1): Ditto.
+
+Fri Jul 20 15:30:26 1990 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * arscan.c (ar_name_equal): Rewritten. Accounts for a possible
+ trailing slash in MEM.
+
+ * remake.c (f_mtime): Keep track of whether ARNAME is used and free it
+ if not. Also free MEMNAME.
+ * ar.c (ar_member_date, ar_touch): Ditto.
+
+ * arscan.c (arscan) [HPUX or hpux]: Treat same as USGr3 PORTAR==1.
+
+ * make.h: If NSIG is not defined, but _NSIG is, #define NSIG _NSIG.
+
+ * compatMakefile: Don't use $* in explicit rules.
+
+ * default.c (default_variables: "PREPROCESS.S"): Include $(CPPFLAGS).
+
+ * remake.c (f_mtime): If FILE is an ar ref, get the member modtime.
+

+
+ * 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
+ instead of ..._idx, and do it right!
+
+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
+ ret value casts to (void *) #ifdef __STDC__ to avoid conflicts btwn
+ ANSI and BSD `signal' and handler types.
+ * main.c (main), job.c (child_handler): Use it.
+
+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.
+ * commands.h: Declare chop_commands.
+ * make.h: Declare uniquize_deps.
+ * main.c (main): Remove unused variable.
+ (decode_switches): Remove unused label.
+ * remake.c: Include "ar.h" for ar_parse_name decl.
+ * implicit.c (try_implicit_rule): Remove unused variable.
+ * function.c (expand_function: `shell'): Declare fork, pipe.
+ * ar.c: Declare ar_name_equal.
+
+ * GNUmakefile: If using gcc, add warning flags to CFLAGS.
+
+ * remake.c: Remove decl of ar_member_date, since it's done in make.h.
+
+ * remake.c (f_mtime): For ar refs, allow the archive to be found via
+ 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.
+
+ * remake.c (f_mtime): After doing rename_file, do check_renamed instead
+ of assuming rename_file will always set FILE->renamed (which it won't).
+
+ * 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
+ file_mtime.
+ (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)
+
+ * ar.c (ar_member_date): Don't free ARNAME since enter_file holds onto
+ the storage.
+
+ * 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).
+
+Fri Jun 22 12:35:37 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * default.c (default_variables): Define `LINK.s' and `LINK.S'.
+ (default_suffix_rules): Define .S.o rule.
+
+ * job.c (construct_command_argv): If we decide to go the slow route,
+ free all storage for the chopped args.
+ (start_job): Free the argument list's storage correctly.
+ construct_command_argv only allocates ARGV and ARGV[0].
+
+Tue Jun 19 18:27:43 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * Version 3.58.4.
+
+Fri Jun 15 21:12:10 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * glob.c: New version from ai-lab which doesn't do [^abc].
+
+Thu Jun 7 00:30:46 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * dir.c: Copied dirent vs direct et al mess from glob.c.
+
+ * glob.c: Replaced with updated version from djm.
+ * glob.c: Check macro DIRENT instead of _POSIX_SOURCE for <dirent.h>.
+ __GNU_LIBRARY__ implies DIRENT and STDC_HEADERS.
+
+Thu May 31 22:19:49 1990 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * vpath.c (vpath_search): Don't stop the loop if a pattern matches but
+ the search fails. All matching patterns have their paths searched
+ (like it says in the manual).
+
+ * make.texinfo (Rules: Directory Search: Selective Search): Say that
+ multiple `vpath' directives with the same pattern DO accumulate, not
+ supersede earlier ones.
+
+ * vpath.c (print_vpath_data_base): Increment the count of vpaths on
+ each loop iteration, rather than letting it stay zero.
+
+ * Version 3.58.3.
+
+ * job.c (block_children, unblock_children): Made static.
+ (push_children_blocked_p, pop_children_blocked_p): New functions to
+ push and pop whether children are blocked or not.
+ * job.h: Declare push_children_blocked_p, pop_children_blocked_p and
+ not block_children, unblock_children.
+ * commands.c (fatal_error_signal), job.c (wait_for_children, new_job,
+ child_execute_job), main.c (main, log_working_directory): Use sequences
+ of push_children_blocked_p (1) and pop_children_blocked_p () instead of
+ 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.

+ in first example.
+ (Implicit: Last Resort): Don't say the .DEFAULT example creates files
+ "silently". It's automatic, but not silent.

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

+
+ * 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)
+
+ * rule.c (new_pattern_rule): Return `int' instead of `void': nonzero if
+ the passed rule was used, zero if not.
+ (install_pattern_rule): Pay attention to the return from
+ new_pattern_rule, and don't set the rule's `terminal' flag or give it
+ commands unless it's used.

+
+ * commands.c (execute_file_commands): Removed unused variable.

+
+ * 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.

+ it is a non-target with no commands.
+
+Fri Sep 1 00:04:39 1989 Roland McGrath (mcgrath at saffron.Berkeley.EDU)
+
+ * read.c (read_all_makefiles): After freeing each element on MAKEFILES,
+ 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.h: Declare it.
+ * main.c (main): Use exec_command when re-execing.
+

+
+Thu Aug 31 18:42:51 1989 Roland McGrath (mcgrath at saffron.Berkeley.EDU)

+ instead of turning it into a space.
+
+ * main.c (main): Do init_siglist #ifdef HAVE_SIGLIST.
+
+ * job.c [WTERMSIG || (USG && !HAVE_SYS_WAIT)]: Test each W* macro

+ * 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'.

+ 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

+
+ * 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

+ * make.texinfo (Commands: Recursion: Variables/Recursion): Document
+ that default variables are not put in the environment.
+

+ 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'

+
+ * 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.

+
+ * 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

+ of sigsetmask.
+
+ * remake.c (notice_finished_file): Under -n or -q, always increment
+ files_remade for non-phony files.
+
+ * rule.c (intall_pattern_rule): Use find_percent.

+ 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

+ * read.c (read_makefile): Don't run find_percent on `vpath' directive
+ patterns.
+
+ * function.c (pattern_matches): Take new arg PERCENT, a pointer into
+ PATTERN where the % is. If PERCENT is nil, copy PATTERN into local

+ 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

+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
+ to do the right thing with an empty path.
+
+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.

+
+ * 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

+
+ * 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

+
+ * remake.c (notice_finished_file): Don't get the new modtime of phony

+Fri Jul 7 18:33:24 1989 Roland McGrath (fsf at void.ai.mit.edu)

+
+ * job.c: If WTERMSIG is defined by <sys/wait.h>, define WAIT_T as int,

+ F versions of $^ and $?.
+
+ * commands.c (start_job): In the child fork, use getdtablesize and a
+ loop to close all file descriptors other than 0, 1, and 2. We need to
+ do this since not only the bad stdin pipe, but also some directories,
+ may be open.
+
+ * 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

+
+ * remake.c (update_file_1): Set the `parent' member of each dependency
+ to FILE before updating it.
+
+ * file.h (struct file): Add `parent' member.

+
+ * variable.h: Declare {allocated_}variable_expand_for_file.
+
+ * variable.c (allocated_variable_expand): Now
+ allocated_variable_expand_for_file, calling variable_expand_for_file,

+
+Fri Jun 9 12:11:45 1989 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * commands.c (start_job): On the child side of the fork, always close
+ the bad stdin file descriptor.
+
+ * commands.c (struct child): New member `environment', to hold the
+ environment for the child.
+ (execute_file_commands): Set the new childs `environment' member to nil
+ before calling start_job.
+ (start_job): Set up CHILD->environment before running the commands if
+ it is nil.
+
+ * make.c (main): Don't call new_environ. `shell' functions will now be
+ run with the environment make was called with.
+
+ * commands.c (child_handler): Don't check C->command_ptr before calling
+ start_job since we now have to check C->file->cmds->command_lines and
+ 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
+ is an array of flags, each nonzero if the corresponding line is
+ recursive.
+
+ * variable.c (variable_expand_for_file): If FILE is nil, just do a
+ vanilla variable_expand.
+ (expand_function: `shell'): Pass second arg (as nil) to
+ construct_command_argv.
+
+ * commands.c (construct_command_argv): Use variable_expand_for_file on
+ `$(SHELL)' and `$(IFS)' instead of lookup_variable to check those
+ variables. This handles file-local and recursive values correctly.
+ 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
+ goal. (When user-level per-file variables are implemented, PARENT
+ 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.
+
+ * variable.h: Don't declare lookup_variable_for_file.
+
+ * variable.c (lookup_variable_*): Turned back into lookup_variable. It
+ now uses current_setlist.
+ (global_setlist): New static `struct variable_set_list', a setlist
+ containing global_variable_set.
+ (current_setlist): New static `struct variable_set_list *', a pointer
+ to the current variable set list.
+ (define_variable): Define in the current top-level set, not the global
+ 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 in the variable set at the top of FILE's chain.
+ (lookup_variable_for_file): New function like lookup_variable, but
+ takes additional arg FILE, and looks the variable up in all of FILE's
+ 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'
+ global_variable_set.
+ (define_variable): Now define_variable_in_set, taking additional
+ argument SET, the `struct variable_set' to define it in.
+ (define_variable): Use define_variable_in_set with global_variable_set.
+ (lookup_variable): Now lookup_variable_in_set, taking additional
+ argument SET, the `struct variable_set' to look it up in.
+ (lookup_variable): Use lookup_variable_in_set with global_variable_set.
+ (lookup_variable_in_setlist): New function to look up a variable in a
+ `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'
+ member.
+
+ * read.c (record_files): Don't check commands from $(MAKE) and set
+ their `recursive' member.
+
+ * commands.c (fatal_error_signal): Treat SIGQUIT like SIGINT, SIGHUP,
+ and SIGTERM, but don't send it to ourselves because it will cause a
+ core dump.

+ (VARIABLE_BUCKETS): Increased to 523.
+
+ * file.c (enter_file, lookup_file, rename_file): Use a smarter hashing
+ algorithm, spreading the bits about somewhat.
+
+ * make.c (log_working_directory): Under `-p', precede the directory
+ message with a `#'.
+
+ * make.c (print_version): Under `-p', precede each line with a `#'.
+ (print_data_base): Precede the header line with a `#' and include the
+ date and time on it.
+
+ * vpath.c (print_vpath_data_base): Precede non-directive

+
+ * dir.c (print_dir_data_base): Precede all lines with `#'s.
+
+ * variable.c (print_variable_data_base): Changed format so that it can
+ be makefile input. Lines that are not variable definitions are
+ preceded with `#'. Nonrecursive variable definitions are made with all
+ dollar signs doubled to reproduce the initial value. Recursive

+ directives. Nonrecursive variable definitions containing newlines, and
+ variable names containing :, =, or newlines, will come out garbled.

+ patsubst_expand so as to avoid find_percent and thus disallow
+ 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.
+

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

+
+ * glob.c (glob_tilde): New global variable (int), defaults to zero.

+ modtimes to NOT make dependencies be considered newer. RCS checks
+ out files with equal modtimes as the RCS files, so this screws it.
+
+ * make.h, glob.c: If __GNUC__ is defined, use __builtin_alloca.
+
+ * Makefile: Use variables `ALLOCA' and `ALLOCASRC' so systems
+ without a good standard alloca can get it from the Emacs

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

+
+ * read.c (read_all_makefiles): Don't set *MAKEFILES to the name of
+ the end of the read_makefiles chain, since the latter may be from an
+ included makefile. (Why did I do this before?)
+
+ * make.c (main): Set argv[0] to "" if it was nil. Don't put the

+ processing all arguments.
+
+ * GNUmakefile: Moved `include depend' to the end, so the default
+ goal will be set before then.
+
+ * load.c (wait_to_start_job [Unix, UMAX]): Merged into one version
+ under #ifdef LDAV_BASED. Only loop while we have jobs running.
+ Sleep for increasing amounts (increase one second per iteration)

+
+Fri Dec 16 16:51:07 1988 Roland McGrath (mcgrath at hecuba.Berkeley.EDU)
+
+ * commands.c (start_job): If start_remote_job_p () returns nonzero,

+ (child_handler):
+
+ * commands.c (execute_file_commands): Moved load average checking to
+ start_job.
+
+ * commands.c (child_handler: USG): Record the pid wait returns.

+
+ * variable.c (define_automatic_variables): Pass all the args to
+ define_variable when defining MAKELEVEL!

+
+Thu Dec 15 15:22:08 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+
+ * Makefile: Renamed to oldMakefile.
+ * GNUmakefile: Make Makefile from oldMakefile and depend.
+
+ * read.c (read_all_makefiles): When putting the default makefiles in
+ the read_makefiles chain so they will be remade, put them in the
+ right order.
+
+ * remake.c (update_goal_chain): If MAKEFILES is nonzero, always make
+ in serial, and return as soon as one goal whose `changed' member is

+ which defines the two variables.
+ * variable.c (define_automatic_variables): Don't define MAKEFLAGS
+ and MFLAGS.

+
+ * 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).
+

+Fri Dec 9 18:44:13 1988 Roland McGrath (mcgrath at pepper.Berkeley.EDU)
+
+ * 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.
+

+
+ * remake.c (check_dep): Set *MUST_MAKE_PTR nonzero if a dependency

+ 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).

+
+ * 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

+
+ * Version 3.21.
+

+
+ * 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

+ 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)

+
+ * GNUmakefile, Makefile: Fixed a typo in a comment.

+
+ * variable.c: Removed old debugging #define's for xmalloc and

+ * 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!
+
+Wed Oct 19 15:07:43 1988 Roland McGrath (mcgrath at pepper.Berkeley.EDU)
+
+ * 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

+ * remake.c (remake_file): Don't increment `files_remade' for a
+ non-target file we don't know how to remake.
+
+ * read.c (record_files): Don't die with "both : and :: entries" for

+
+ * variable.c (expand_function: `patsubst'): Don't clobber the

+ second argument correctly.
+
+ * ar.c (ar_touch): Return 1 rather than -1 for on errors.
+
+Sat Oct 15 15:12:16 1988 Roland McGrath (mcgrath at homer.Berkeley.EDU)
+

+ 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

+
+ * 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.
+
+Fri Oct 14 18:35:00 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * read.c (read_all_makefiles): Pass second arg to read_makefile for

+
+Thu Oct 13 16:40:08 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * Version 3.13.
+
+ * GNUmakefile: Added an explicit rule for make.dvi since the
+ built-in .texinfo.dvi implicit rule is screwed up.
+

+ 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.
+
+ * commands.c (struct child): Added `good_stdin' flag to tell if this

+ `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.
+

+ files used for standard input makefiles.
+
+ * make.c (main): Don't turn standard input into a broken pipe.
+

+ 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.

+ * commands.c (execute_file_commands): Use noticed_finished_file
+ after waiting for the child when there is only one job slot.

+ and such things to be done when commands finish.
+ (update_file_1): Use notice_finished_file.
+
+ * commands.c (child_handler, execute_file_commands): Use new
+ variable `job_slots_used' to record the number of jobs currently
+ 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.

+
+ * file.h (struct file): Add `dontcare' member.
+
+ * read.c (read_all_makefiles): When no default makefiles are found,
+ put the names of all those tried in the `read_makefiles' chain so
+ they will be updated if possible, giving their `struct dep's'
+ `changed' members the value of 0 so we won't care if they cannot be
+ found or remade.
+
+ * make.texinfo (Makefiles: Remaking Makefiles): Documented that
+ default makefiles will be remade if not found.
+
+ * read.c (read_all_makefiles): If no default makefiles can be found,

+
+ * remake.c (remake_file): Set STATUS to 0 after successfully touching.
+
+ * dir.c (file_impossible, file_impossible_p): Don't clobber FILENAME

+
+ * Version 3.11.

+
+Mon Oct 3 16:14:39 1988 Roland McGrath (mcgrath at paris.Berkeley.EDU)
+
+ * make.c (main): Try to move back to the directory we started in

+
+ * remake.c (update_file_1): A double-colon target with no deps
+ always needs to be remade.
+
+ * remake.c (remake_file): Changed "No way to make" message to say
+ `target' rather than `file'.
+
+Sun Oct 2 12:50:47 1988 Roland McGrath (mcgrath at catnip.Berkeley.EDU)
+
+ * remake.c (update_file_1): Set FILE->update_status to the return

+ on their `updated' flag, not their state.
+
+ * read.c (read_makefile): Don't check for FILENAME being "-".
+ (read_all_makefiles): Set each element of MAKEFILES to the name put
+ in READ_MAKEFILES by read_makefile, since read_makefile may free the

+ the elements of MAKEFILES again.
+
+ * make.c (main): For each `-f' flag with arg `-' (standard input),
+ read standard input into a temp file and pass the temp file's name
+ to read_all_makefiles, after making sure it will not be remade.

+
+ * read.c (find_makefile): Removed this function.
+ (read_all_makefiles): Don't update makefiles, don't diddle with
+ pattern rules, don't call snap_deps, etc. Return a `struct dep'
+ 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

+ leaving multiple `struct dep's with the same pointers.
+
+Thu Sep 29 19:08:13 1988 Roland McGrath (mcgrath at catnip.Berkeley.EDU)
+
+ * make.c (decode_switches): Fixed second decode_env_switches call to
+ use correct length of "MFLAGS" (6, not 5).
+
+ * read.c (read_makefile): Don't stop reading when readline returns
+ zero lines read. Only stop when the stream reaches EOF. This makes
+ it recognize the last line of a makefile without a newline.
+
+ * remake.c (remake_file): If we don't know how to make FILE, set its
+ command state to `cs_finished'.
+
+ * remake.c (update_file): Don't write the "up to date" message if

+ for `commands' and `command_ptr' members.
+
+ * make.c (decode_env_switches): Skip past an invalid letter (instead

+ (execute_file_commands): Get a new environment from new_environ and
+ 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.

+ (execute_file_commands, kill_children): Use wait_for_children.
+
+ * 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

+ 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.

+
+ * make.c (decode_switches): Fixed an xrealloc call with no first arg.

+ * make.texinfo: Documented parallelism.
+
+Fri Sep 23 16:52:27 1988 Roland McGrath (mcgrath at helen.Berkeley.EDU)
+
+ * remake.c (update_file_1): Don't return if FILE's state is

+
+ * commands.c (start_job): Made it set the state to `cs_running'.

+
+ * commands.c (fatal_error_signal): Don't swallow all the children
+ with a loop around `wait ((union wait *) 0)'!!!
+
+ * make.c (struct command_switch): Added `positive_int' type.
+ (switches): Added -j (job_slots).
+ (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
+ reading in all makefiles (the last time it will be needed).
+

+ (execute_file_commands): Merged run_file_commands back in.
+ 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

+
+ * 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.

+ 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_makefile): Get the modtime of the makefile via a stat
+ call so that a later file_mtime call won't do VPATH search for it.
+
+ * read.c (read_makefile): Don't turn off -t and -q if the makefile
+ was a command-line target.
+
+ * make.c (main): Enter command-line targets as files and set their

+
+ * read.c (read_makefile): Temporarily turn off -t and -q while
+ updating makefiles.

+ * 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

+
+ * read.c (read_all_makefiles): Made it not look at the `MAKE'

+ included makefiles, pass this as zero. Now returns nonzero if the
+ makefile was updated, zero if not.
+ (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

+ * make.c (main): Print version info for -v, -p, or -d.
+ (print_data_base): Don't print version info. It will be done in main.

+
+ * variable.c (print_variable_data_base): Fixed bug which made -p

+ * 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.
+
+ * variable.c (try_variable_definition): Fixed a bug which made it
+ 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,
+ default_variables): Added .texinfo.info rule.
+ * make.texinfo (Implicit: Catalogue of Rules): Documented
+ .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.
+
+Sat Jul 23 17:32:55 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * rule.c (default_suffixes, default_suffix_rules): Added rule
+ to make %.dvi from %.texinfo.
+
+ * dir.c (print_dir_data_base): Made it say a bit more.
+
+Fri Jul 22 23:13:16 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * make.c (print_data_base): Split this function up into one
+ for each thing.
+ * variable.c (print_variable_data_base): One of the above.
+ * rule.c (print_rule_data_base): Ditto.
+ * file.c (print_file_data_base): Ditto.
+ * dir.c (print_dir_data_base): Ditto.
+
+ * 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.
+
+Fri Jul 15 21:01:44 1988 Roland McGrath (mcgrath at tully.Berkeley.EDU)
+
+ * Took Make out of RCS.
+
+ * Split the monolithic `make.c' into several smaller files.
