But this assumes that // comments are not recognized in C, whereas
the new C standard says they should be.

My example was independent of which version of C is used.  But it
was a bit long-winded, so here's a slightly simpler version:

#include <stdio.h>
typedef int foo;
int main()
{
    struct foo { int x,y; };
    printf("C%s\n", sizeof(foo)==sizeof(int) ? "" : "++");
    return 0;
}
