[PATCH 1/9] Reimport gnulib from scratch.
- From: Pedro Alves <palves at redhat dot com>
- To: gdb-patches at sourceware dot org
- Date: Thu, 27 Jun 2013 19:52:07 +0100
- Subject: [PATCH 1/9] Reimport gnulib from scratch.
- References: <20130627185200 dot 6625 dot 10526 dot stgit at brno dot lan>
I tried moving aside gnulib/import/, and re-running the our
gnulib/update-gnulib.sh script, and surprisingly, I get a different
result compared to what's in the tree. This is with pristine FSF
autoconf and FSF automake, at the versions required by
update-gnulib.sh. However, if I just run the update-gnulib.sh scripts
against the _existing_ tree, then nothing changes... I suspect
gnulib-tool's merge logic might be preserving some things by design.
I think we should put this in regardless, as a "get rid of cruft that
might have accumulated over gnulib updates". onceonly.m4 seems to fit
in that category.
I'd go as far as suggesting that update-gnulib.sh itself could/should
rebuild the import directory from scratch.

-dnl AC_REQUIRE([AC_FUNC_STRCOLL]) like AC_FUNC_STRCOLL
-dnl The advantage is that the check for each of the headers/functions/decls
-dnl will be put only once into the 'configure' file. It keeps the size of
-dnl the 'configure' file down, and avoids redundant output when 'configure'
-dnl is run.
-dnl The drawback is that the checks cannot be conditionalized. If you write
-dnl if some_condition; then gl_CHECK_HEADERS(stdlib.h); fi
-dnl inside an AC_DEFUNed function, the gl_CHECK_HEADERS macro call expands to
-dnl empty, and the check will be inserted before the body of the AC_DEFUNed
-dnl function.
-
-dnl The original code implemented AC_CHECK_HEADERS_ONCE and AC_CHECK_FUNCS_ONCE
-dnl in terms of AC_DEFUN and AC_REQUIRE. This implementation uses diversions to
-dnl named sections DEFAULTS and INIT_PREPARE in order to check all requested
-dnl headers at once, thus reducing the size of 'configure'. It is known to work
-dnl with autoconf 2.57..2.62 at least . The size reduction is ca. 9%.
-
-dnl Autoconf version 2.59 plus gnulib is required; this file is not needed
-dnl with Autoconf 2.60 or greater. But note that autoconf's implementation of
-dnl AC_CHECK_DECLS_ONCE expects a comma-separated list of symbols as first
-dnl argument!
