The question of the repository it belongs in is separate from the question of how it's built.  In FreeBSD, the code is likely to remain in a library that's called libgcc_s.so or libgcc_eh.a, as that's required for backwards compatibility.

I'd be interested to hear what these headaches are, to see if we can avoid them in the future.
