Patch for native networking code (IPv6)

[Geoff Berry]

This patch fixes a typo and adds a missing check in the native
networking code that only cause problems if we HAVE_INET6.
Incidentally, has anyone gotten libgcj to compile on a glibc2.1 Debian
system?

1999-04-08  Geoff Berry  <gcb@gnu.org>

	* natInetAddress.cc (lookup): Fix typo (AF_INET16 -> AF_INET6).
	* natPlainSocketImpl.cc (accept): Add missing else if check
	for AF_INET6.
