Added test for property attribute encodings. These are based on the Apple documentation here:
http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/ObjCRuntimeGuide/Articles/ocrtPropertyIntrospection.html Several of the things in the documentation are wrong: - The encoding of structures does not include the field names in property encodings. This encoding format appears to only be used in ivars (yes, it is frustrating) - Apple appears to encode long as q on LP64 platforms. This is probably a compiler bug. - The N flag is not set for non-atomic properties. This appears to be a clang bug, since the non-atomic flag is not set in the AST - both the Mac and GNUstep runtimes generate the same wrong result. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/base/trunk@32944 72102866-910b-0410-8b05-ffd578937521
