Toplevel config/override.m4 should already cause failure if you use anything other than Autoconf 2.64 (but it doesn't ensure Automake 1.11). However, if override.m4 isn't included in some directory (because that hasn't been done yet, or because somebody ran aclocal with missing -I arguments), then the test isn't used. So it's debatable whether AC_PREREQ would help for that case. Since we pretty much require override.m4 to fix a bug in 2.64, however, that doesn't really gain us all that much. Better to just ensure it is used everywhere. A few followup patches to binutils ensure Automake 1.11 there. I can write one to ensure it in GCC as well (or think about a way to do it in override.m4) if that is desired. Cheers, Ralf
