[gcjx] Patch: FYI: Initial gcjx checkin

[Tom Tromey <tromey at redhat dot com>]

I'm checking in gcjx to the gcjx-branch of gcc.gnu.org and declaring
the sourceforge repository dead.  I'm not posting the patch here as it
is rather large.  There will actually be two such checkins, one for
the gcjx front end itself (in the top-level directory 'gcjx') and
another for the tree back end, in gcc/java.

The branch won't be buildable after this, as not all the configury
code has been written.  It is probably possible to build gcjx in
isolation, but I haven't tested this yet either.

I intend to send gcjx patches to this list, with '[gcjx]' in the
Subject.
