I agree that enabling libjava by default for mingw should wait for after branch. Until then I think an explicit  --enable-libgcj should be required.

Since Ranjit's original bug report, I have tried several time to build libgcj natively, in order to verify that it should be enabled by default.  Including libgcj broke bootstrap, not always but often enough for me to have doubts about stability of libgcj builds on mingw.   I can't attempt to test now because the windows box to which I have access  has only 512MB physical memory and that has long been a personal showstopper for native libgcj builds.
