regex: deprecate the obsolete macro AM_WITH_REGEX
This is a backport of commit v1.11-433-g37b0aee.
Today, practically nobody uses the GNU rx library, which, according
to its own website <http://www.gnu.org/software/rx/rx.html>, has
been "decommissioned". Consequently, the automake-provided macro
AM_WITH_REGEX is not used nor required anymore. Deprecate it, so
that it will be possible to safely remove it in the next major
automake version.
* m4/regex.m4 (AM_WITH_REGEX): Give a warning of the class
`obsolete' when this macro is used.
* doc/automake.texi (Public Macros): Move description of
`AM_WITH_REGEX' from here ...
(Obsolete Macros): ... to here, and declare it as obsolete
and "to be removed in a future version".
* tests/regex-obsolete.test: New test.
* tests/Makefile.am (TESTS): Add it.
* NEWS: Update.
