Remove obsolete AC_HEADER_STDC autoconf macro
It does nothing useful since a long time any more and just triggers warnings from autoconf 2.71 and later.
Just a trivial change to avoid warnings like this from autogen.sh
:
configure.ac:123: warning: The macro `AC_HEADER_STDC' is obsolete.
configure.ac:123: You should run autoupdate.
./lib/autoconf/headers.m4:704: AC_HEADER_STDC is expanded from...
configure.ac:123: the top level
Note that there are still
libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,
libtoolize: and rerunning libtoolize and aclocal.
libtoolize: Consider adding '-I m4' to ACLOCAL_AMFLAGS in Makefile.am.
remaining, but I'm not sure if the maintainers really want to add m4
directory (I suspect that if they did, they would have already done it?), so I didn't follow this advice.
