It will skip the runtime support for GCJ and libffi.  So you won't be
able to do anything with GCJ.  I recall a discussion on the GCC list 
about a release policy to only enable libjava on platforms where it was
known to work (as opposed to disabling it on platforms where it was known
to fail).  It takes a long time to build so failures are particuarly annoying.

I don't remember any problems building 2.95.3.  Since cc1obj links against
a lot of common code in GCC, you need to do a whole build.

It's a loose end, but I think a harmless one.  (I assume you are talking
about the Cygwin source tarball.)

Hmm, no, I think that's worked ok for me for quite a while.  I'd try
the latest Cygwin DLLs.  Something might turn up from a mailing list
search, too.
