Ok, maybe gpsd is not impacted by the libraries it is using, but it
seems libgps is using some time_t fields, so they would need to be
replaced by int64_t or something to avoid breaking libgps applications
that don't use the same time_t.

I'm not aware of any glibc-based distributions that made the
switch yet. It seems Gentoo is considering few different options:

On rpm-based systems the flags might appear in output of "rpm -E
%{build_cflags}", but we won't know for sure until it happens.
