Patch: embedded libjava -vs- natSystem changes

[Tom Tromey]

I'm committing this patch.  It changes embedded ports of libgcj so
that they don't use getuid() or getcwd().

We need to do something better here, but that will have to wait until
I have (or somebody has) time to really think about it.

1999-12-15  Tom Tromey  <tromey@cygnus.com>

	* java/lang/natSystem.cc (init_properties): Don't set user.name or
	user.home if NO_GETUID defined.  Only set user.dir if getcwd
	exists.

	* include/config.h.in: Rebuilt.
	* acconfig.h (NO_GETUID): New define.
	* configure.in: Rebuilt.
	* configure.in: Define NO_GETUID in cross case.  Check for getcwd
	in native case.
