Latest autoconf has something wrong with the language macro. Executing autoconf gives (tested for different packages or standalone); aclocal.m4:672: error: m4_defn: undefined macro: _m4_divert_diversion autoconf/lang.m4:173: AC_LANG_RESTORE is expanded from... aclocal.m4:672: the top level I went back to 7.1 rpms which are all working (automake and libtool as well)
Which version-release of autoconf and automake gave you trouble? Also could you attach a simple configure.in file that gives the error.
