Is the following legal?

	char * foo;
	while ((volatile)foo)
		continue;

If legal, what does (volatile)foo mean -- is it
(volatile char *)foo or (volatile int)foo?  The former
would be more useful.  The spec seems to say it is
legal but I can not find anything about its meaning.

BTW, is anyone working on a denotational semantics
definition of ANSI C (or a major subset of it)?  Don't
laugh.

Thanks!
