4874 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
4875 generation rules. Wrap all rules that change the current
4876 directory in parentheses; pmake doesn't spawn a new shell for

4879 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
4880 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
4881 and beyond.
4883 * objc/Make-lang.in: Wrap all rules that change the current

11824 * fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
11825 output file with the temporary one by appending ".X" to generate
11826 the temporary fuile's name. If the output file already has an
11827 extension, replace it with ".X".
11829 * fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
11830 not $DESTDIR, to find applyfix. Use sprintf instead of snprintf;
11831 reallocate the command buffer while copying the command-line

11833 instead of going through another temporary file.
11834 (process): Close the temporary file before unlinking it.
11835 (machine_matches) [__MSDOS__]: If the machine doesn't match, set
11836 the FD_SKIP_TEST flag. Pay attention to the FD_MACH_IFNOT flag.
11837 (run_compiles): Pass p_fixd argument to machine_matches, as it
11838 expects.
11840 * fixinc/fixincl.sh: Export ORIGDIR. If $DJDIR is set in the

11842 directory. When cleaning up the DONE files, look for them
11843 case-insensitively. Don't try to remove symlinks if they aren't
11844 there.
11846 * fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
11847 all callers changed. Declare pz "const char *", to avoid compiler
11848 warnings.
11850 * fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.
11851 Change prototype of make_raw_shell_str.

11860 return stdout.

11864 * fixinc/fix*.[ch]: substantially reworked to make it possible
11865 to run this program without using fork(2) or pipe(2) (i.e. in

11878 if the offset is large and negative, and we are compiling
