I got: (cd /files/mitchell/gcc_auto_build/gcc/libf2c/libI77 && autoheader) /bin/sh: autoheader: not found It looks like stamp-h.in is not in CVS or created by gcc_update, with the result that if you don't have autoheader you are out of luck. -- Mark Mitchell mark@codesourcery.com CodeSourcery, LLC http://www.codesourcery.com
