This problem needs to be fixed in gcc 3.0. In the worst case, we can
use the stop-gap of not using _Jv_AllocBytes to allocate the
hash-table, but instead using a function allocates scanned memory, but
that means intern'd strings are never reclaimed.  However, that is
better than the current situation.

Well, I think the situation is improved now, at least on Linux.
I'm able to build, and almost able to compile Kawa.  (Still a
problem when compiling class files.)  I do have a couple more
patches I hope to check in today.
