That's not a macro, it's an inlined function. The reason the nil
doesn't work is for the same reason it wouldn't work in any other
function. Namely, you're only modifying the argument (which is a copy)
and not the original variable. If you really wanted a macro, it would
look like this:
#define GDRelease(x) do { [(x) release]; (x) = nil; } while (0)
