Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>: - 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.

/* $NetBSD: cdefs.h,v 1.7 1997/11/04 23:09:58 thorpej Exp $ */
This file, which will be included by <sys/cdefs.h>, will contain macros such as __warn_references() and __weak_reference() which are actually machine dependant. This will make it easier for ports that are being bootstraped with ELF and ECOFF based toolchains. This change also introduces a new macro, _C_LABEL(x). _C_LABEL expands its argument, an identifier, to a character string of the identifier name as it is represented in an object file. For most ports, _C_LABEL(x) will expand to "_x", for ELF based ports _C_LABEL(x) will expand to "x".
