Yes, that's right.

You have to ask the gcc maintainers this question. The libgcj hackers
really only deal with the gcj front end; generic gcc questions have to
be handled via the other gcc developers.

I agree with you. In fact this is a problem because it means you have
to rebuild libgcc for every different OS; without threads you can use
a single gcc to target any OS running on a given target.
The other night it occurred to me that just using spinlocks in this
code might be reasonable (depending on how long the lock is going to
be held), or at least a reasonable alternativ.
