g++ -vs- libgcj

[Tom Tromey <tromey at cygnus dot com>]

The current g++ can't compile libgcj:

I'd like to recommend that C++ front end changes be used to rebuild
libgcj on a regular basis.  libgcj uses some g++ features that nobody
else uses (e.g., `extern "Java"').  We see g++ breakage much more
frequently than we'd like.
