1386         invisible reference in registers, but then spilled to the stack.
1387         Remove code to emit a second stab for such parameters; it attempts
1388         to describe the value's location by introducing a synthetic C++
1389         `reference' type, and then saying the stack slot has that
1390         reference type.  This loses type information (breaking GDB's
1391         `ptype' command, among other things) just to describe a location
1392         which stabs can represent correctly in other ways.

4748         $srcdir/$s/Makefile.in in all_lang_makefiles, but do include
4749         $outputs.  Do not run configure.lang from config.status.
4750         Rearrange warning-flag logic to correspond to what the
4751         makefile wants.  Put special vax stage1 options in

4763         STRICT1_WARN, STRICT2_WARN -> $(@D)-warn, GCC_WARN_CFLAGS ->
4764         WARN_CFLAGS.  Distinguish STAGE1_CFLAGS from BOOT_CFLAGS.
4765         Add -I$(@D) and -I$(srcdir)/$(@D) to INCLUDES.

4768         generation rules.  Wrap all rules that change the current
4769         directory in parentheses; pmake doesn't spawn a new shell for
4770         each command.  Expunge all references to $(P).  When one
4771         command depends on another and they're run all at once, use &&
4772         to separate them, not ;.  Add libgcc_s$(SHLIB_EXT) to files
4773         deleted on make clean.  Force OUTPUT_OPTION='-o $@' in stage2
4774         and beyond.

4779         once, use && to separate them, not ;.  Add OUTPUT_OPTION to

11712         the UNIX functionality and applied the next three patches
11713         from July:
11714
11715 2000-07-28  Eli Zaretskii  <eliz@is.elta.co.il>
11716
11717         * fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
11718         output file with the temporary one by appending ".X" to generate
11719         the temporary fuile's name.  If the output file already has an
11720         extension, replace it with ".X".
11721
11722         * fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
11723         not $DESTDIR, to find applyfix.  Use sprintf instead of snprintf;
11724         reallocate the command buffer while copying the command-line
11725         argument.  Redirect the output directly to the temporary file,
11726         instead of going through another temporary file.
11727         (process): Close the temporary file before unlinking it.
11728         (machine_matches) [__MSDOS__]: If the machine doesn't match, set
11729         the FD_SKIP_TEST flag.  Pay attention to the FD_MACH_IFNOT flag.
11730         (run_compiles): Pass p_fixd argument to machine_matches, as it
11731         expects.
11732
11733         * fixinc/fixincl.sh: Export ORIGDIR.  If $DJDIR is set in the
11734         environment, assume there are no symlinks in the include
11735         directory.  When cleaning up the DONE files, look for them
11736         case-insensitively.  Don't try to remove symlinks if they aren't
11737         there.
11738
11739         * fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
11740         all callers changed.  Declare pz "const char *", to avoid compiler
11741         warnings.
11742
11743         * fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.
11744         Change prototype of make_raw_shell_str.
11745
11746 2000-07-27  Eli Zaretskii  <eliz@is.elta.co.il>
11747
11748         * fixinc/fixincl.c [__MSDOS__]: Don't include "server.h".
11749         (initialize) [__MSDOS__]: Use tempnam.
11750         (initialize): Don't use SIGPIPE if it is not defined.
11751
11752         * fixinc/fixfixes.c (main) [__MSDOS__]: freopen for stdout should
11753         return stdout.
11754
11755 2000-07-25  Bruce Korb  <bkorb@gnu.org>
11756
11757         * fixinc/fix*.[ch]: substantially reworked to make it possible
11758         to run this program without using fork(2) or pipe(2) (i.e. in
11759         a DOS environment).
11760
11761 2000-08-04  Joseph S. Myers  <jsm28@cam.ac.uk>

11771         if the offset is large and negative, and we are compiling
11772         for 64 bit registers.
