2013-12-31 Marcus Mueller <znek@mulle-kybernetik.com>
* Headers/Foundation/NSMetadata.h: use GS_PROTOCOLS_HAVE_OPTIONAL for
NSMetadataQueryDelegate. Always define the protocol, even if it's empty
(so we don't have to adjust any headers), but fallback to the informal
protocol if OS version < 10.6 OR compiler doesn't support @optional
keyword in protocols.

* Headers/GNUstepBase/GSVersionMacros.h: added macros
