Could be.  I've found that sometimes I need to compile without optimizations
or in debug mode or else certain things aren't exported properly.  Those look
like gcc manglings.  What compiler are you using?  It might be easier to
use 'nm'.  When I use bcc I use tlib to generate a listing of exports.

Probably not.

I've thought about it, but haven't had the time to do so.  Also, there 
never seemed to be very much demand for it outside of my own projects.

I don't doubt that it could, but I don't know anything about Objective C
or its ABI.
