So it seems that boehm-gc is in the exact state as libffi.

This is yet another example of why we shouldn't duplicate sources...

Hans, would you be willing to bring boehm-gc up to speed so that we
can start getting it to work for Win64?  Without this, we obviously
cannot add gcj to our list of supported compilers.
