+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
