Does it work to use the following test program instead? int find_stack_direction (char *addr) { char dummy; return (! addr ? find_stack_direction (&dummy) : addr < &dummy ? 1 : -1); }
int main (void) { return find_stack_direction (0) < 0; } This, essentially, is the fix I just pushed into the GNU autoconf trunk, here: http://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=b1747413a80add0271d6909aecfdc2b638456257
