Xcode 4 comes with a version of clang that treats inline differently: it requires exactly one definition of the inline function in the linked unit. static inline is C99-compliant (according to LeoNerd in freenode/##c) and does not have this problem, so use that in objc_darwin.h instead.

Fixes issue 1.
