>Description:
	C function renaming using __RENAME() macro won't work
	with gcc  -traditional  option.

>How-To-Repeat:

% ed foo.c
foo.c: No such file or directory
a
#include <unistd.h>
main()
{
	vfork();
	return 0;
}
.
w
52
q
% cc -traditional foo.c
/tmp/cc00260a.s: Assembler messages:
/tmp/cc00260a.s:11: Error: Ignoring junk after expression


% cc -traditional -E foo.c | grep __asm__
pid_t	 vfork ()			__asm__("_C_LABEL(__vfork14)");
						^^^ This is wrong

% cc -E foo.c | grep __asm__
pid_t	 vfork  (void)  			__asm__("___vfork14"  ) ;
							^^^ This is correct

>Fix:
	Change  __RENAME  macro definition like this???

	#ifdef __GNUC__
	#ifdef __STDC__
	#define	__RENAME(x)	__asm__(___STRING(_C_LABEL(x)))
	#else
	#define	__RENAME(x)	__asm__(_/**/x)
	#endif
	#endif
