Automake-1.13 removed long obsolete AM_CONFIG_HEADER completely ( http://lists.gnu.org/archive/html/automake/2012-12/msg00038.html ) and errors out upon seeing it. Attached patch replaces it with proper AC_CONFIG_HEADERS. I'm not subscribed to mailing list. ---- I'm mass-submitting automake-1.13 fixes. Please see what you can do so I don't need to do the same when automake-1.14 comes out: http://cazfi.livejournal.com/195108.html - ML
