I don't observe the problem on either Fedora 15 or Ubuntu 12.04
compiled for x86 (these used signed 32-bit time_t).  I tried both
gcc 4.6.3 and gcc 4.7.1 (which is the latest stable version).

If memory serves, warnings like that occur only with older GCCs and
are harmless, and the GCC folks fixed the bogus warnings after the
gnulib folks complained about them.  Maybe time to upgrade your GCC?
