| | | | | | | | | Problem reported by Gavin Smith in: https://lists.gnu.org/r/autoconf/2020-09/msg00012.html * m4/extensions.m4 ([gl_USE_SYSTEM_EXTENSIONS]): Require AC_GNU_SOURCE only for Autoconf 2.63 and earlier, since it shouldn’t be needed after that, and Autoconf 2.70 complains about it being obsolete.

* Assume gnulib is checked out from Git, not CVSStefano Lattarini2013-05-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In fact, access to the gnulib repository through CVS has been disabled, or more precisely, got broken and was never restored; see: <http://lists.gnu.org/archive/html/bug-gnulib/2013-05/msg00008.html> Note that support for CVS is not removed completely and unthinkingly by this change: only support for CVS checkouts of gnulib itself is removed. For example, the 'bootstrap' script still cater to .cvsingore files and CVS directories, for the benefit of those poor gnulib clients still stuck with CVS. Ditto for the 'gnulib-tool' script itself. * gnulib-tool: Simplify accordingly. * posix-modules: Likewise. * MODULES.html.sh: Likewise. * doc/gnulib.texi: No longer mention the decommissioned CVS gnulib repository. * doc/gnulib-intro.texi: Likewise. * doc/gnulib-readme.texi: Likewise. * doc/gnulib-tool.texi: In the examples and explanations, refer to a sample '.gitignore' file rather than a sample '.cvsignore'. * NEWS: Update. * m4/extensions.m4: While at it, remove a comment mistakenly referring to "CVS Autoconf" rather than "git Autoconf".

* extensions: port better to HP-UXPaul Eggert2013-02-081-6/+23
| | | | | | | This is merged from git Autoconf. * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): On hosts that need _XOPEN_SOURCE, define it when configuring, too, so that it's compatible with the value used when compiling.
* extensions: port better to MINUX 3, HP-UX, autoheader 2.62Paul Eggert2013-02-061-15/+13
| | | | | | | | | | Some of these changes are merged in from git Autoconf. * m4/extensions.m4 (AC_USE_SYSTEM_EXTENSIONS): When deciding whether to define _XOPEN_SOURCE, inspect the preprocessor macro __hpux instead of the more-heavyweight operation of requiring AC_CANONICAL_HOST. Define _NETBSD_HOST on MINUX, for MINUX 3. Use USE_SYSTEM_EXTENSIONS, not __EXTENSIONS__, as the key for __EXTENSIONS__.
