The only thing necessary should be the GCCMain one that is being kept up
to date by Tom in the rhug repository:
http://sourceware.org/cgi-bin/cvsweb.cgi/eclipse-gcj/org/eclipse/jdt/internal/compiler/batch/GCCMain.java?cvsroot=rhug
Latest version is r34_1, haven't yet tried if it also applies to 3.4.2.

If that works out then it would be good to update the recommended
version of ecj-latest.jar that the gcc/contrib/download_ecj grabs so
that future versions (4.4?) of gcc will come with it.

Cheers,

Mark
