It's similar.

If we're going to compile all the .calss files in a lump I'm tempted
to try the same thing with compiling libgcj from source.  We'd do lots
of inlining and avoid many PLT indirections.  I suppose compiling all
of libgcj this way would probably be out of the question, but pieces
with good locality might work well.
