Alas, this is the effect of defining _XOPEN_SOURCE in configure.in.
This somehow has the effect of not defining these symbols in
pyconfig.h:

HAVE_STRUCT_TM_TM_ZONE
HAVE_TM_ZONE
HAVE_TZNAME

I'm going to remove the _XOPEN_SOURCE define; Jeremy and Martin can
try to figure out what the right thing is for Tru64.
