I've got a question about libatomic_ops,
Wouldn't it be easier to let libatomic_ops be a submodule of boehm_gc and
Use `git submodule update --init --recursive' or `git clone --recursive (when initially cloning mercury)'
Since the prepare script uses cp on Windows, one must manually update the libatomic_ops/* copied files
