Comparing Selectors

I have an issue with comparing selectors. Trouble is, the GNU Objective-C
runtime tells me that SEL's are pointers to struct objc_selector and that they
themselves may not be unique, and the correct way to compare them is by doing:

sel1->sel_id == sel2->sel_id

However, Apple forums and according to what I read about the Apple Objective-C
runtime, doing just

sel1 == sel2

is perfectly fine and that the uniqueness of both selectors is ensured.

So please, can anybody tell me what is the correct, civilized and portable way
of doing it?
