[LLVMdev] How do you determine whether a function is definedexternally to a module ?

This is not working. For some reason there is a BasicBlock present on 
undefined functions !

I am compiling the examples from llvm/test/feature, about 28 out of 34 
assemble fine. Just cannot seem to get the externals listed, been trying for 
several hours :(

I will have a look at this then.
