Which platform? Oh, I see from your error messages it's Linux.

That doesn't seem right. Just from looking at your link errors I can see
that it's libgcc2 which is using pthreads. I'm pretty sure people have been
successfully using this toolset on Linux.

Does this happen with any compilers other than 2.96? I ask because that's
not an official GCC release... though we should probably support it since
RedHat shipped it <grrrr>. Either way, I think you need to do a more
careful analysis of the problem before we try to fix it.

Suggestion: post a separate message for each of the failing libraries, with
that library's name in the header. That will be more likely to raise the
author's attention.

Try the suggestion above.
