You mean it "fails to keep c constant"?  Without the `const's, that code
_should_ assign 0 to `c'.  If the const should be errored about, then the
failure is not reporting the const error.

What is the defined behavior with "volatile const"?  Is it defined as the
same as "volatile"--that is, no const behavior at all?

FWIW, the SunPro C++ for Solaris is the same as gcc/egcs.

: extern "C" int printf(const char *, ...);
: int main(int, char **)
: {
: 	volatile const int c = 42;
: 	volatile int *p;
: 	volatile const int *&r = p;
: 	r = &c;
: 	*p = 0;
: 	if (c != 42)
: 		printf("FAILED!\n");
: }
