>  - removed gcc-fortran provides from gcc-libs, as we had a sobump
>  - changed gcc-gcj to upstream tarballs instead of Ubuntu branch
>  - rebuilt gjdoc which is a native java program
>  - updated java-gcj-compat
>  - rebuilt all fortran applications against new gcc-libs and changed

Huh? We need to patch a lot of C++ source code that relies on C includes?

>  As gcc 4.3 should be backwards compatible with 4.2 (except for libgcj
