In that case, I don't see how you can be seeing the behaviour that you are 
seeing.  The compiler is seeing GSEnumeratorBlock as a block type, so it will 
never be generating type encodings for it as a structure.  The only thing that 
I can think of is that you somehow did not do a completely clean build.
