source: trunk/m4/yat_add_flag.m4 @ 775

Last change on this file since 775 was 775, checked in by Peter Johansson, 12 years ago

moving m4 files to directory m4/. NOTE this change will break Makefiles, so you need to issue 'autoreconf -m'. Also adding a longlong.m4 that seems to have been missing before(?).
