Please review a fix for 8007748: MacOSX build error : cast of type 'SEL' to 'uintptr_t' (aka 'unsigned long') is deprecated; use sel_getName instead

SEL is defined thusly:
typedef struct objc_selector *SEL;
I would have a hard time believing Apple could change that without breaking everything that's currently written in Objective-C. The opaque parts could change, which is likely why the warning is showing up, or maybe they're just enforcing better coding practices.
> The code can run into a problem if Apple change the underlying type of SEL to something completely different (and larger) than a void* pointer. However, I think this is unlikely to happen.
> The evaluation sounds reasonable to me, so consider the fix reviewed.
