- fix _C_LABEL so that it actually works. - make __RENAME use _C_LABEL. - fix __RENAME so that it expects an unquoted argument. - fix __indr_reference and __warn_references so that they supply their own final semicolon. - define __warn_references to nothing if not GNU C (required by the way it's used). The __warn_references semicolon change has to be made so that __warn_references can be defined into nothing. (A ; all by itself isn't a great idea.) The __indr_reference change was made for consistency.
