2014 `reference' type, and then saying the stack slot has that
2015 reference type. This loses type information (breaking GDB's
2016 `ptype' command, among other things) just to describe a location
2017 which stabs can represent correctly in other ways.

5392 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
5393 generation rules. Wrap all rules that change the current
5394 directory in parentheses; pmake doesn't spawn a new shell for

5396 command depends on another and they're run all at once, use &&

12345 extension, replace it with ".X".
12347 * fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
12348 not $DESTDIR, to find applyfix. Use sprintf instead of snprintf;

12351 instead of going through another temporary file.
12352 (process): Close the temporary file before unlinking it.

12360 directory. When cleaning up the DONE files, look for them
12361 case-insensitively. Don't try to remove symlinks if they aren't
12362 there.
12364 * fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
12365 all callers changed. Declare pz "const char *", to avoid compiler
