26+ should work better with C23, which removed the non-prototyped K&R

5MIME-Version: 1.0

9AC_XENIX_DIR is an obsolete macro, defined as AC_HEADER_DIRENT plus
10code to make absolutely sure configure scripts that depended on a
11shell variable internal to the original (2.13 era) definition of
12AC_XENIX_DIR are not broken by autoupdate. (That variable had the
13temptingly public-sounding name “XENIX.”) This compatibility code
14uses AC_EGREP_CPP, which is itself discouraged for use in new
15configure scripts.
16
17(N.B. codesearch.debian.net does not find any uses whatsoever of
18this macro, nor any code in an .ac or .m4 file that depends on the
19XENIX variable.)
20
21Change the compatibility code to use AC_CANONICAL_HOST instead,
22and clarify which pieces of the code inserted by autoupdate are
23probably still necessary.
24
25* lib/autoconf/specific.m4 (AC_XENIX_DIR): Set XENIX variable
26 based on value of host_os. Clarify what manual cleanup is
27 recommended after autoupdate replaces this obsolete macro.

9AC_TYPE_UID_T uses AC_EGREP_HEADER to search sys/types.h for
10occurrences of the string ‘uid_t’ and, if found, assumes both
11uid_t and gid_t are available. This would be better done using
12a pair of AC_CHECK_TYPE operations.
13
14I also converted two uses of old-style AC_CHECK_TYPE, immediately
15below, to new-style. (There are probably other old-style uses in
16this file, I only did the ones I happened to see.)
17
18* lib/autoconf/types.m4 (AC_TYPE_UID_T): Check for uid_t and gid_t,
19 separately, using AC_CHECK_TYPE, instead of grepping sys/types.h.
20 (AC_TYPE_SIZE_T, AC_TYPE_SSIZE_T): Use new-style AC_CHECK_TYPE.

10This macro is one of the last remaining internal uses of AC_EGREP_CPP.
11It has only ever done anything useful with GCC, and GCC dropped
12support for ‘traditional’ compilation in version 3.3 (released 2003)
13so I do not think it is worth trying to preserve.
14
15* lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Make into a
16 compatibility alias for AC_PROG_CC, similar to AC_PROG_CC_STDC.
17* lib/autoconf/general.m4 (AC_EGREP_CPP): Remove stale comment.
18* doc/autoconf.texi, NEWS: Document this change.
19* tests/mktests.pl: Exclude AC_PROG_GCC_TRADITIONAL from
20 autoupdate tests.

4Subject: [PATCH 12/29] Overhaul AC_TYPE_GETGROUPS and AC_FUNC_GETGROUPS.
5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
9AC_TYPE_GETGROUPS is the last remaining use of AC_EGREP_HEADER in
10stock Autoconf macros. It uses it only when cross compiling, as a
11fallback from an AC_RUN_IFELSE check, testing for a bug in system
12headers from the late 1980s or early 1990s, where gid_t *existed*
13but the second argument to getgroups needed to be an array of int,
14and this didn’t cause a compile error (i.e. the system headers
15declare getgroups with no prototype or an incorrect prototype).
16AC_FUNC_GETGROUPS also uses AC_RUN_IFELSE to test for obscure
17problems specific to long-obsolete Unixes.
18
19The downsides of AC_RUN_IFELSE and AC_EGREP_HEADER seem more severe
20than the chances of someone compiling a current-generation program,
21that uses getgroups, on an OS old enough to have one of the really
22nasty bugs. Accordingly, this patch changes AC_FUNC_GETGROUPS to use
23a host_os-based *blacklist* both in native and cross compilation.
24This is limited to the two host_os values for which either our old
25code, or Gnulib, documented a serious bug: ultrix* and nextstep*.
26Currently it does not try to pin down the exact version ranges subject
27to the bugs — that would require research by someone with access to
28the full history of these OSes.
29
30An incorrect guess by this blacklist can be overridden by setting
31ac_cv_func_getgroups_works in config.site. AC_TYPE_GETGROUPS, for its
32part, now does a series of regular old AC_COMPILE_IFELSE checks to
33probe the prototype of getgroups, and considers that good enough.
34
35While I was in there I noticed that AC_FUNC_GETGROUPS does not
36AC_SUBST a documented output variable, and that the name of this
37variable is misspelled in the manual.
38
39* lib/autoconf/functions.m4 (AC_FUNC_GETGROUPS): Use AC_SEARCH_LIBS
40 to probe for getgroups. Use an AC_CANONICAL_HOST-based blacklist
41 for bug detection, not AC_RUN_IFELSE. AC_SUBST the GETGROUPS_LIB
42 output variable.
43* lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Check only the prototype
44 of getgroups, using AC_COMPILE_IFELSE; do not use either AC_RUN_IFELSE
45 or AC_EGREP_HEADER.
46* doc/autoconf.texi: Update to match. Correct misspelling of
47 GETGROUPS_LIB.
48* tests.local.at (_AT_CHECK_ENV): Allow GETGROUPS_LIB output variable.

7Content-Transfer-Encoding: 8bit

9Another of the last few uses of AC_EGREP_CPP is to check for the ISO C
10“stringification” operator. As this is a feature of C89, let’s fold
11the test into the extensive C89 tests we already have, and make
12AC_C_STRINGIZE just lean on AC_PROG_CC, in the same way
13AC_C_PROTOTYPES does.
14
15* lib/autoconf/c.m4 (_AC_C_C89_TEST_GLOBALS): Add test of preprocessor
16 stringification and token pasting.
17 (AC_C_STRINGIZE): Just check ac_prog_cc_stdc.

4Subject: [PATCH 14/29] Remove the last few internal uses of AC_EGREP_CPP.
5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
9Most of the remaining uses were converted to AC_COMPILE_IFELSE.
10The use in AC_FUNC_LOADAVG becomes an AC_PREPROC_IFELSE because
11we can’t be sure getloadavg.c can be _compiled_ at this point in
12the build. The use in AC_C_VARARRAYS could be either _PREPROC_ or
13_COMPILE_; we use _COMPILE_ because, _PREPROC_ is never used, then
14we don’t have to do the “checking how to run the C preprocessor” test.
15
16* lib/autoconf/c.m4 (AC_C_VARARRAYS): Use AC_COMPILE_IFELSE instead of
17 AC_EGREP_CPP.
18* lib/autoconf/headers.m4 (_AC_HEADER_TIOCGWINSZ_IN_TERMIOS_H)
19 (_AC_HEADER_TIOCGWINSZ_IN_SYS_IOCTL_H): Likewise.
20* lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use AC_PREPROC_IFELSE
21 instead of AC_EGREP_CPP.

17Similarly for enable_year2038.

5
6New macro AC_SYS_YEAR2038_RECOMMENDED replaces new macro
7AC_SYS_YEAR2038_REQUIRED, and gives the builder an out of
8specifying --disable-year2038. Remove new macro
9AC_SYS_LARGEFILE_REQUIRED, which was added only for symmetry and
10does not seem to have a great need.
11* NEWS, doc/autoconf.texi: Document this.
12* lib/autoconf/specific.m4:
13Be more specific about mid-January 2038 than just Jan 2038.
14(_AC_SYS_YEAR2038_PROBE): Ignore IF-NOT-DETECTED arg.
15If support is not detected, merely set ac_have_year2038=no instead
16of erroring out. All callers changed.
17(_AC_SYS_YEAR2038_OPT_IN): Remove. All callers removed.
18(AC_SYS_YEAR2038): Simplify by requiring AC_SYS_LARGEFILE
19and then testing the result.
20(AC_SYS_YEAR2038_REQUIRED, AC_SYS_LARGEFILE_REQUIRED): Remove.
21(AC_SYS_YEAR2038_RECOMMENDED): New macro.
22(_AC_SYS_LARGEFILE_PROBE): If support is not detected, merely set
23ac_have_largefile=no instead of erroring out. All callers changed.
24Take on the burden of invoking year2038 probe as needed.
25(AC_SYS_LARGEFILE): Simplify.

9* lib/autoconf/functions.m4 (AC_FUNC_MMAP): Don’t call
10getpagesize, as it’s tricky to configure, modern POSIX doesn’t
11require it, and calling it without including <unistd.h> provokes a
12compile-time error on modern systems. Instead, rework the test
13to not need getpagesize. Add a FIXME comment for unnecessary
14tests; I don't want to remove them now as we're too close to
15a release. Remove long-obsolete comment about GNU grep.

10https://lists.gnu.org/r/bug-autoconf/2023-05/msg00005.html
11* lib/autoconf/functions.m4 (AC_FUNC_MMAP): Go back to getting the
12page size, since the zero-fill test needs this after all.
13However, prefer sysconf (_SC_PAGESIZE) or sysconf (_SC_PAGE_SIZE)
14to getpagesize (), and use ‘long’ not ‘int’ to store the page size.
15Also, declare getpagesize if it is used as a function.

10Instead, mention that 32-bit time_t is not recommended

12to configure with 32-bit time_t anyway.

5MIME-Version: 1.0
6Content-Type: text/plain; charset=UTF-8
7Content-Transfer-Encoding: 8bit
8
9Rewrite install.texi so that INSTALL is shorter and hopefully
10more useful for new installers.
11* doc/install.texi: When not building the Autoconf manual, put
12copyright notice at the end, and omit external references as they
13do not work in INSTALL.
14Avoid long URLs as they do not work well in INSTALL or
15in info files. Be more consistent (though not entirely
16consistent) about “system” vs “architecture”.
17(System Types, Building for a different system type)
18(Troubleshooting the Build Type): Coalesce into a single section
19and rewrite for clarity and brevity. Mention build-aux. Do not
20mention --target here as it’s too rare to make the cut.
