+
+	* Version 3.75.91
+
+Fri Aug 15 13:50:54 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* read.c (do_define): Remember to count the newline after the endef.
+
+Thu Aug 14 23:14:37 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* many: Rewrote builds to use Automake 1.2.
+
+	* AUTHORS: New file.
+	* maintMakefile: Contains maintainer-only make snippets.
+	* GNUmakefile: This now only runs the initial auto* tools.
+	* COPYING,texinfo.tex,mkinstalldirs,install-sh: Removed (obtained
+	automatically by automake).
+	* compatMakefile: Removed (not needed anymore).
+	* README,build.sh.in: Removed (built from templates).
+	* config.h.in,Makefile.in: Removed (built by tools).
+
+Wed Aug 13 02:22:08 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* make.texinfo: Updates for DOS/Windows information (Eli Zaretskii)
+	* README,README.DOS: Ditto.
+
+	* remake.c (update_file_1,f_mtime): Fix GPATH handling.
+	* vpath.c (gpath_search): Ditto.
+
+	* file.c (rename_file): New function: rehash, but also rename to
+	the hashname.
+	* filedef.h: Declare it.
+
+	* variable.c (merge_variable_set_lists): Remove free() of variable
+	set; since various files can share variable sets we don't want to
+	free them here.
+
+Tue Aug 12 10:51:54 1997  Paul D. Smith  <psmith@baynetworks.com>
+
+	* configure.in: Require autoconf 2.12
+
+	* make.texinfo: Replace all "cd subdir; $(MAKE)" examples with a
+	more stylistically correct "cd subdir && $(MAKE)".
+
+	* main.c: Global variable `clock_skew_detected' defined.
+	(main): Print final warning if it's set.
+	* make.h: Declare it.
+	* remake.c (f_mtime): Test and set it.
+
+	* job.c (start_job_command): Add special optimizations for
+ 	"do-nothing" rules, containing just the shell no-op ":".  This is
+ 	useful for timestamp files and can make a real difference if you
+ 	have a lot of them (requested by Fergus Henderson <fjh@cs.mu.oz.au>).
+
+	* configure.in,Makefile.in: Rewrote to use the new autoconf
+	program_transform_name macro.
+
+	* function.c (function_strip): Strip newlines as well as spaces
+	and TABs.
+
+Fri Jun  6 23:41:04 1997  Rob Tulloh <rob_tulloh@tivoli.com>
+
+	* remake.c (f_mtime): Datestamps on FAT-based files are rounded to
+	even seconds when stored, so if the date check fails on WINDOWS32
+	 systems, see if this "off-by-one" error is the problem.
+
+	* General: If your TZ environment variable is not set correctly
+	then all your timestamps will be off by hours.  So, set it!

+
+	* glob: Updates from latest GNU libc glob code.
+
+	* glob.c,glob.h,fnmatch.h: Change all WIN32 references to WINDOWS32.
+
+	* glob.h: OSF4 defines macros in such a way that GLOB_ALTDIRFUNC
+	is not defined.  Added a test to the #if which defines it if
+	_GNU_SOURCE is defined; that's set by both glob.c and GNU make.
+
+	* glob.c: SunOS4 w/ cc needs #include <stdio.h>, since assert.h
+	requires stderr but doesn't include stdio.h :-/.
+	(next_brace_sub): De-protoize function definition.
+	(glob): Cast __alloca(); on SunOS4 it uses the default return type
+	of int.
+	(glob): Irix defines getlogin_r() to return a char*; move the
+	extern for that into the _LIBC area since it isn't used except in
+	LIBC anyway.  Likewise, move extern getlogin() into the "else".

+@cindex @code{SHELL}, MS-DOS specifics
+The processing of lines that set the variable @code{SHELL} in Makefiles
+is different on MS-DOS.  The stock shell, @file{command.com}, is
+ridiculously limited in its functionality and many users of @code{make}
+tend to install a replacement shell.  Therefore, on MS-DOS, @code{make}
+examines the value of @code{SHELL}, and changes its behavior based on
+whether it points to a Unix-style or DOS-style shell.  This allows
+reasonable functionality even if @code{SHELL} points to
+@file{command.com}.
+
+If @code{SHELL} points to a Unix-style shell, @code{make} on MS-DOS
+additionally checks whether that shell can indeed be found; if not, it
+ignores the line that sets @code{SHELL}.  In MS-DOS, GNU @code{make}
+searches for the shell in the following places:

+@enumerate

+@end enumerate
+
+In every directory it examines, @code{make} will first look for the
+specific file (@file{sh} in the example above).  If this is not found,
+it will also look in that directory for that file with one of the known
+extensions which identify executable files.  For example @file{.exe},
+@file{.com}, @file{.bat}, @file{.btm}, @file{.sh}, and some others.
+
+If any of these attempts is successful, the value of @code{SHELL} will
+be set to the full pathname of the shell as found.  However, if none of
+these is found, the value of @code{SHELL} will not be changed, and thus
+the line that sets it will be effectively ignored.  This is so
+@code{make} will only support features specific to a Unix-style shell if
+such a shell is actually installed on the system where @code{make} runs.
+
+Note that this extended search for the shell is limited to the cases
+where @code{SHELL} is set from the Makefile; if it is set in the
+environment or command line, you are expected to set it to the full
+pathname of the shell, exactly as things are on Unix.
+
+The effect of the above DOS-specific processing is that a Makefile that
+says @samp{SHELL = /bin/sh} (as many Unix makefiles do), will work
