[Benjamin Kosnik]

Due to src/Makefile.am's libstdc++.INC rule re-appearing... if you revert 

2000-12-05  Alexandre Petit-Bianco  <apbianco@redhat.com>

        * src/Makefile.am (libstdc++.INC): Revert for libjava builds.
        * src/Makefile.in: Regenerate.

Things should work again. Can you try this please?
