which leads to the following code being well-formed and well-defined
in both C89 and C99 but having different semantics...

#include <stdio.h>

int
main(void)
{
        int a, b, c;

        a = 10;
        b = 2;
        c = a //* oops! */
            -b;
        switch (c) {
	case 8:
                printf("C99 or C++\n");
		break;
	case -5:
                printf("C89\n");
		break;
	default:
		printf("can't happen\n");
		break;
	}
        return 0;
}

This is actually documented in the C99 rationale.
