Sorry.  I was already kind of annoyed that I had to explicitly enable
Java for my own tests for a while, and got desperate upon the
possibility of having to do it too when installing the final release
of GCC 3.0 on 15+ platforms :-)

It's already disabled on less popular systems, and on systems in which
it hasn't been tested.  Look for ${libgcj} in assignments to
noconfigdirs in the top-level configure.in and you'll get a feeling of
what I'm talking about.  Even if we enable GCJ by default, only a few
platforms will get all of the libjava stuff built along with it.
Regardless of --enable-languages.  It's quite likely that libjava is
only enabled on platforms in which it's known to work.  By enabling
the Java language by default, we'll be making sure that to be the
case.  By not enabling it, it's quite likely that some people (myself
included) will try to build with
--enable-languages=lots,of,languages,plus,java (because there's no
other way to enable some language in addition to the default ones)
and, after the full bootstrap and libstdc++ build, will end up
learning that libjava fails to build on their platform, instead of
being told at configure time that libjava is known to be unsupported,
and thus disabled.

How about doing it the other way round, taking into account that
libgcj is already disabled for almost all platforms: enable GCJ by
default, and, whenever we get a report that it fails to build on some
platform, we disable it?
