Patch attached. I am not sure whether HAVE_GETOPT is the best condition
to use, since it's set by configure by a link based check, same goes for
HAVE_INT_OPTERR. The other choices would be relying on HAVE_GETOPT_H or
a new AC_CHECK_DECL.

I haven't touched entab.c because it's not linking with pgport, so there
seems little use in changing it.

I've also removed some #ifndef WIN32's that didn't seem to make much sense.
