- * 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.

- 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.
-

- all callers changed. Declare pz "const char *", to avoid compiler
- warnings.
