Hi, I apologize that I write in two pieces again. You often use: m4_eval(_AC_SED_CMD_NUM+1) Are you aware of m4_incr(_AC_SED_CMD_NUM) ? I think it's more readable, but your preferences might differ. Yours, Stepan _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
