Well, I was hoping to encourage someone to fix the few remaining bugs

Oh dear. As far as I know it used to work, so the most likely
explanation is that there's a common fault that breaks everything.

This is not my experience. However, if there really are people
interested in using gcj on hppa-linux in its current semi-broken
state, then perhaps they can build with --enable-languages. But at
the moment it doesn't look like we have a working
MD_FALLBACK_FRAME_STATE_FOR, and we really need that for proper
I suppose I'm mostly concerned about gcj's reputation as a decent Java
platform. But if you really believe that enabling Java by default on
hppa-linux might get it working faster, I'll acquiesce.
