--- Comment #4 from Manfred Schwarb <manfred99 at gmx dot ch> ---
But why remove something that works even after year 2038?
It seems that the underlying c-routine works also beyond year 2038.

Relaxing the integer check in gfc_check_ltime_gmtime() and calling
gmtime_i8 instead of gmtime_i4 in gfc_resolve_gmtime() depending on the
argument type would make things work, I guess.

I'm not familiar enough with this intrinsic machinery to provide a patch,
unfortunately.
