2000-08-04 Bruce Korb <bkorb@gnu.org>
* fixinc/: Verified that the MSDOS patch does not break
the UNIX functionality and applied the next three patches
from July:
2000-07-28 Eli Zaretskii <eliz@is.elta.co.il>
* fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
output file with the temporary one by appending ".X" to generate
the temporary fuile's name. If the output file already has an
extension, replace it with ".X".
* fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
not $DESTDIR, to find applyfix. Use sprintf instead of snprintf;
reallocate the command buffer while copying the command-line
argument. Redirect the output directly to the temporary file,
instead of going through another temporary file.
(process): Close the temporary file before unlinking it.
(machine_matches) [__MSDOS__]: If the machine doesn't match, set
the FD_SKIP_TEST flag. Pay attention to the FD_MACH_IFNOT flag.
(run_compiles): Pass p_fixd argument to machine_matches, as it
expects.
* fixinc/fixincl.sh: Export ORIGDIR. If $DJDIR is set in the
environment, assume there are no symlinks in the include
directory. When cleaning up the DONE files, look for them
case-insensitively. Don't try to remove symlinks if they aren't
there.
* fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
all callers changed. Declare pz "const char *", to avoid compiler
warnings.
* fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.
Change prototype of make_raw_shell_str.
2000-07-27 Eli Zaretskii <eliz@is.elta.co.il>
* fixinc/fixincl.c [__MSDOS__]: Don't include "server.h".
(initialize) [__MSDOS__]: Use tempnam.
(initialize): Don't use SIGPIPE if it is not defined.
* fixinc/fixfixes.c (main) [__MSDOS__]: freopen for stdout should
return stdout.
2000-07-25 Bruce Korb <bkorb@gnu.org>
* fixinc/fix*.[ch]: substantially reworked to make it possible
to run this program without using fork(2) or pipe(2) (i.e. in
a DOS environment).
2000-08-04 Joseph S. Myers <jsm28@cam.ac.uk>
* cppdefault.h (WINT_TYPE): Define.
