That didn't see to give me any trouble. But I have run into problems with
linking in NSPR. After quite a fun time discovering the limitations of
dynamic libs on OS X, I'm making a Spidermonkey static lib to use. I've
added nspr4.a, the OS X static version of the NSPR lib to that project. It
compiles fine, but when I try to use the library, I get link errors. The
missing pieces seem to be:

Restfp and savefp, referenced from balloc
_umoddi3 and _udivdi3 from 'fill2'

I can't find these in the nspr source code.

Does this ring a bell?

Thanks,

Bruce
