Failing to build with the core patch.

Anthony, 

I'm (eventually) testing your patch. I'm trying to build your proposed
extension of libjava and it fails with:

(I'm building on Alpha/linux.) The Makefile{,am,in} appears to be OK,
listing gnu/gcj/protocol/core/natCoreInputStream.cc and such but it
never seems to build. If I touch an other new file, such as
gnu/gcj/natCore.cc, then natCore.cc gets rebuild.

Am I missing something?
