1627 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
1628 invisible reference in registers, but then spilled to the stack.

5009 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
5010 generation rules. Wrap all rules that change the current
5011 directory in parentheses; pmake doesn't spawn a new shell for
5012 each command. Expunge all references to $(P). When one
5013 command depends on another and they're run all at once, use &&
5014 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
5015 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
5016 and beyond.
5018 * objc/Make-lang.in: Wrap all rules that change the current
5019 directory in parentheses. Expunge all references to $(P).

11959 * fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
11960 output file with the temporary one by appending ".X" to generate
11961 the temporary fuile's name. If the output file already has an
11962 extension, replace it with ".X".
11964 * fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
11965 not $DESTDIR, to find applyfix. Use sprintf instead of snprintf;
11966 reallocate the command buffer while copying the command-line
11967 argument. Redirect the output directly to the temporary file,
11968 instead of going through another temporary file.
11969 (process): Close the temporary file before unlinking it.
11970 (machine_matches) [__MSDOS__]: If the machine doesn't match, set
11971 the FD_SKIP_TEST flag. Pay attention to the FD_MACH_IFNOT flag.
11972 (run_compiles): Pass p_fixd argument to machine_matches, as it
11973 expects.
11975 * fixinc/fixincl.sh: Export ORIGDIR. If $DJDIR is set in the
11976 environment, assume there are no symlinks in the include
11977 directory. When cleaning up the DONE files, look for them
11978 case-insensitively. Don't try to remove symlinks if they aren't
11979 there.
11981 * fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
11982 all callers changed. Declare pz "const char *", to avoid compiler
11983 warnings.
11985 * fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.
11986 Change prototype of make_raw_shell_str.

11995 return stdout.
11997 2000-07-25 Bruce Korb <bkorb@gnu.org>
11999 * fixinc/fix*.[ch]: substantially reworked to make it possible
12000 to run this program without using fork(2) or pipe(2) (i.e. in
12001 a DOS environment).
