Uh, oh, that bug looks like a major annoyance in 64bit! I made a 
few checks, all appkit methods returning a NSRect currently 
produce a runtime segfault. But this does not apply to NSSize, 
nor NSPoint, functions returning either NSSize or NSPoint work.

What I have found out so far: all the extern C functions in 
geometry.d work just fine.. e.g. NSRectFromString does what it's 
supposed to do.
