[ difficulty of implementing 'noalias' at the last minute ]

Back to an older suggestion: it might be easier (and better defined ?-)
(politically, not technically) to define pragma() behavior than noalias

	noalias char	*cp;
vs.
	pragma(noalias) char	*cp;

While the latter is certainly more verbose, I think that it changes the
language less, and of course it can be taken out (in existing C compilers,
for backwards compatability) for _all_ pragmas with

	#define	pragma(x)

Or if "pragma" is already taken, consider "hint", which accurately
describes what's going on . . .

	;-D on  (Well it sure *sounded* sound at the time)  Pardo
