Ok, so I tried to be fancy and do this: AS_VAR_APPEND([SYSHEAD_LIST],[AS_ECHO([$srcdir/include/sys/*.h])]) But that results in $SYSHEAD_LIST being equal to "printf". Darn.

Am I not using AS_VAR_APPEND right? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
