Ok.

Nope, not yet.

Please make a .i file for mandel.c (clang -E mandel.c > mandel.i) and  
send it to the list.

This isn't in the clang tree.

This looks like a platform specific difference between your objc.h and  
hte mac one, can you please attach your objc.h so that we can see what  
it looks like?

Likewise, looks like your objc.h doesn't have objc_selector in it?
