Now even 64 bit systems should be able to compile and run GNUstep gui
and back again. But be aware that due to the usage of proxies for named
images (Yes, even when no theme is used!) and a bug in libffi that
hasn't been officially fixed, named images wont be displayed on 64 bit
systems. As we are now using CGFloats in many places and CGFloat is now
a double and libffi wont handle structures and arrays of double
correctly, we get an issue when ever we pass such structures via
NSInvocation. The proxy mechanism for NSImage just exposes this issue.
