When I try to `./autogen.sh --quick' CVS gettext, using git Autoconf,
things fall over like this (several instances):
| gnulib-m4/openmp.m4:29: error: m4_copy: won't overwrite defined macro:
_AC_LANG_OPENMP(C++)
| gnulib-m4/openmp.m4:29: the top level
| autom4te: /usr/bin/m4 failed with exit status: 1
| aclocal: autom4te failed with exit status: 1
I'm not quite sure whether an Autoconf bug/incompatibility is involved
here (therefore the Cc: to bug-autoconf). m4_copy wasn't documented in
earlier Autoconf releases, but there may still have been problematic
semantic changes, I don't know.
Anyway, the following patch seems to fix it. OK to apply?
Cheers,
Ralf
