Problem building libgcj-2.95

[Oleg Moroz]

This one is easy: 1) Cygwin b20.1 headers do not declare in_addr_t (which
should be unsigned long), and 2) cygwin/in.h defines some of the IPv6 thigs
w/o full support for it, so configure picks up HAVE_INET6 which it
shouldn't. Quick and dirty fixes work.

There are couple more minor quirks as well - first, the make process tries
to invoke /bin/pwd, which isn't there in the default installation of Cygwin,
and then natGregorianCalendar.c (file name from memory) tries to use
variable "timezone" (which clashes with the function name) instead of
"_timezone".

After fixing these, libgcj 2.95 builds OK under Mumit Khan's port of gcc
2.95 to cygwin.

There are some troubles with linking programs with gcj though that I can't
yet fix; this is all on my home computer, so I'll investigate more this
night.
