Nonetheless, changing AC_FUNC_MMAP to help that majority, perhaps marginally, breaks programs relying on the check as it stands. Reader survey: Do you know of a program other than GNU grep that depends on AC_FUNC_MMAP to reject the mmap of some system as unsuitable? Put another way, do you know of a program that would stop working on at least one system were you to replace `AC_FUNC_MMAP' with `AC_CHECK_FUNC([mmap])'? _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
