This looks right.

I never do `make bootstrap'.  That didn't used to work.  Maybe it does
now, though.

This means that the libgcj jar file was not correctly installed.
Look in $prefix/install/share.  If `libgcj.jar' does not appear there,
then that is the problem.

Hmm... Warren says you still have to edit the toplevel configure.  See
step 4 here:

This hackery will go away once Alex has fixed the ABI problems.  This
will happen soon.
