That's pretty funny that you encounter this AC_FUNC_MKTIME bug now which
when I encountered it asked about it on the GCC list and which caused this
gigantic thread (and sometime later the overflow warnings were implemented,
see <http://gcc.gnu.org/gcc-4.2/changes.html> for a high-level description).

Anyway, here's the thread and also the patch that fixed this in Autoconf
(unfortunately, you still have to wait for the next stable release :-(
