--- Comment #5 from Martin Sebor <msebor at gcc dot gnu.org> --- I find the POSIX requirement to fail when n is greater than INT_MAX to be in conflict with C. I've submitted a defect to the Austin Group: http://austingroupbugs.net/view.php?id=1219 At the same time, the POSIX requirement makes sense to me since it makes the function safer. So I've also brought this up in WG14 to see if C would be willing to adopt the POSIX requirement.
