It was deliberate. The postgresql guys noticed when some release redhat
shipped with these modifications. They tried to convince the glibc guys to
revert but they refused.
Basically, POSIX doesn't define mktime() before 1970, so glibc doesn't
support it. Or so the argument goes.
IIRC, postgresql has now copied the mktime code from FreeBSDs libc to deal
with the problem. Or maybe they're just thinking about it.
