Thanks for the info and clarification.  I didn't mean to pick on GDL2  
here;  I had just gotten the impression from experimenting with  
various things that the runtime API is used in a number of places  
outside of -base, and sometimes it was not clear why.  I think part of  
this impression may have come from GSObjCRuntime.h getting pulled in  
by GSCategories.h in cases where it is not necessarily needed.  This  
is why I was attempting to eliminate that #include.

In any case, it looked to me like there may be a lot of work to do wrt  
supporting the GSObjCRuntime.h interface on the Apple's Obj-C 2.0  
runtime (which is probably really only needed to support 64-bit;  I  
can't see them removing the old APIs in the 32-bit version any time  
soon).
