1823 from July:
1825 2000-07-28 Eli Zaretskii <eliz@is.elta.co.il>
1827 * fixinc/fixfixes.c (main) [__MSDOS__]: Avoid overwriting the
1828 output file with the temporary one by appending ".X" to generate
1829 the temporary fuile's name. If the output file already has an
1830 extension, replace it with ".X".
1832 * fixinc/fixincl.c (fix_with_system) [__MSDOS__]: Use $ORIGDIR,
1833 not $DESTDIR, to find applyfix. Use sprintf instead of snprintf;
1834 reallocate the command buffer while copying the command-line
1835 argument. Redirect the output directly to the temporary file,
1836 instead of going through another temporary file.
1837 (process): Close the temporary file before unlinking it.
1838 (machine_matches) [__MSDOS__]: If the machine doesn't match, set
1839 the FD_SKIP_TEST flag. Pay attention to the FD_MACH_IFNOT flag.
1840 (run_compiles): Pass p_fixd argument to machine_matches, as it
1841 expects.
1843 * fixinc/fixincl.sh: Export ORIGDIR. If $DJDIR is set in the
1844 environment, assume there are no symlinks in the include
1845 directory. When cleaning up the DONE files, look for them
1846 case-insensitively. Don't try to remove symlinks if they aren't
1847 there.
1849 * fixinc/fixlib.c (make_raw_shell_str): Accept new argument smax;
1850 all callers changed. Declare pz "const char *", to avoid compiler
1851 warnings.
1853 * fixinc/fixlib.h (ENV_TABLE): Get ORIGDIR from the environment.
1854 Change prototype of make_raw_shell_str.
1856 2000-07-27 Eli Zaretskii <eliz@is.elta.co.il>
1858 * fixinc/fixincl.c [__MSDOS__]: Don't include "server.h".
1859 (initialize) [__MSDOS__]: Use tempnam.
1860 (initialize): Don't use SIGPIPE if it is not defined.
1862 * fixinc/fixfixes.c (main) [__MSDOS__]: freopen for stdout should
1863 return stdout.
1865 2000-07-25 Bruce Korb <bkorb@gnu.org>
1867 * fixinc/fix*.[ch]: substantially reworked to make it possible
1868 to run this program without using fork(2) or pipe(2) (i.e. in
1869 a DOS environment).

1881 if the offset is large and negative, and we are compiling
1882 for 64 bit registers.
1884 2000-08-04 Herman A.J. ten Brugge <Haj.Ten.Brugge@net.HCC.nl>
1886 * gencodes.c (main): Define CODE_FOR_nothing as the last possible
1887 insn_code_number + 1.
