We have strategies on the drawing board for dealing with inline asm,
which is the main culprit for now. The other stuff is being worked on,
albeit slowly due to other matters (read: life etc.) getting in the
way.

As for the second part of your question, I'd say it's possible, but
the amount of indirect trouble that may be incurred is likely to be
too big.  I haven't thought about that much though, so perhaps I'm
just too pessimistic.

Jeroen, O'Brien mentioned he would be happy to attempt an integration
of tcc into the FreeBSD build process when the time comes. Perhaps you
could have a little chat with him, he had concrete ideas on how to go
about it the best way (perhaps he's lurking here anyway?).
