721 * dbxout.c (dbxout_parms): Correctly describe parameters passed by
722 invisible reference in registers, but then spilled to the stack.
723 Remove code to emit a second stab for such parameters; it attempts
724 to describe the value's location by introducing a synthetic C++
725 `reference' type, and then saying the stack slot has that
726 reference type. This loses type information (breaking GDB's
727 `ptype' command, among other things) just to describe a location

4103 LANG_FLAGS_TO_PASS. Add OUTPUT_OPTION to all object-file
4104 generation rules. Wrap all rules that change the current
4105 directory in parentheses; pmake doesn't spawn a new shell for
4106 each command. Expunge all references to $(P). When one
4107 command depends on another and they're run all at once, use &&
4108 to separate them, not ;. Add libgcc_s$(SHLIB_EXT) to files
4109 deleted on make clean. Force OUTPUT_OPTION='-o $@' in stage2
4110 and beyond.
4112 * objc/Make-lang.in: Wrap all rules that change the current
4113 directory in parentheses. Expunge all references to $(P).

11051 2000-07-28 Eli Zaretskii <eliz@is.elta.co.il>
11053 * fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
11054 output file with the temporary one by appending ".X" to generate
11055 the temporary fuile's name. If the output file already has an
11056 extension, replace it with ".X".
11058 * fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
11059 not $DESTDIR, to find applyfix. Use sprintf instead of snprintf;
11060 reallocate the command buffer while copying the command-line
11061 argument. Redirect the output directly to the temporary file,
11062 instead of going through another temporary file.
11063 (process): Close the temporary file before unlinking it.
11064 (machine_matches) [__MSDOS__]: If the machine doesn't match, set
11065 the FD_SKIP_TEST flag. Pay attention to the FD_MACH_IFNOT flag.
11066 (run_compiles): Pass p_fixd argument to machine_matches, as it
11067 expects.
11069 * fixinc/fixincl.sh: Export ORIGDIR. If $DJDIR is set in the
11070 environment, assume there are no symlinks in the include
11071 directory. When cleaning up the DONE files, look for them
11072 case-insensitively. Don't try to remove symlinks if they aren't
11073 there.
11075 * fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
11076 all callers changed. Declare pz "const char *", to avoid compiler
11077 warnings.
11079 * fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.
11080 Change prototype of make_raw_shell_str.
11082 2000-07-27 Eli Zaretskii <eliz@is.elta.co.il>
11084 * fixinc/fixincl.c [__MSDOS__]: Don't include "server.h".
11085 (initialize) [__MSDOS__]: Use tempnam.
11086 (initialize): Don't use SIGPIPE if it is not defined.

11089 return stdout.
11091 2000-07-25 Bruce Korb <bkorb@gnu.org>
11093 * fixinc/fix*.[ch]: substantially reworked to make it possible
11094 to run this program without using fork(2) or pipe(2) (i.e. in
11095 a DOS environment).

11107 if the offset is large and negative, and we are compiling
