If using the Boehm GC, then you are using the GCC runtime.  In this case, 
NSAllocateCollectable() will be using objc_malloc().  If using the GNUstep or 
Apple runtimes, objc_malloc() is not implemented, and we have no way of 
distinguishing whether objc_malloc() should wrap NSAllocateCollectable() with 
the scanned option, without the scanned option, or malloc().
