12342	* fixinc/:  Verified that the MSDOS patch does not break
12343	the UNIX functionality and applied the next three patches
12344	from July:
12345
123462000-07-28  Eli Zaretskii  <eliz@is.elta.co.il>
12347
12348	* fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
12349	output file with the temporary one by appending ".X" to generate
12350	the temporary fuile's name.  If the output file already has an
12351	extension, replace it with ".X".
12352
12353	* fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
12354	not $DESTDIR, to find applyfix.  Use sprintf instead of snprintf;
12355	reallocate the command buffer while copying the command-line
12356	argument.  Redirect the output directly to the temporary file,
12357	instead of going through another temporary file.
12358	(process): Close the temporary file before unlinking it.
12359	(machine_matches) [__MSDOS__]: If the machine doesn't match, set
12360	the FD_SKIP_TEST flag.  Pay attention to the FD_MACH_IFNOT flag.
12361	(run_compiles): Pass p_fixd argument to machine_matches, as it
12362	expects.
12363
12364	* fixinc/fixincl.sh: Export ORIGDIR.  If $DJDIR is set in the
12365	environment, assume there are no symlinks in the include
12366	directory.  When cleaning up the DONE files, look for them
12367	case-insensitively.  Don't try to remove symlinks if they aren't
12368	there.
12369
12370	* fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
12371	all callers changed.  Declare pz "const char *", to avoid compiler
12372	warnings.
12373
12374	* fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.
12375	Change prototype of make_raw_shell_str.
12376
123772000-07-27  Eli Zaretskii  <eliz@is.elta.co.il>
12378
12379	* fixinc/fixincl.c [__MSDOS__]: Don't include "server.h".
12380	(initialize) [__MSDOS__]: Use tempnam.
12381	(initialize): Don't use SIGPIPE if it is not defined.
12382
12383	* fixinc/fixfixes.c (main) [__MSDOS__]: freopen for stdout should
12384	return stdout.
12385
123862000-07-25  Bruce Korb  <bkorb@gnu.org>
12387
12388	* fixinc/fix*.[ch]: substantially reworked to make it possible
12389	to run this program without using fork(2) or pipe(2) (i.e. in
12390	a DOS environment).
