In C enum values aren't the types of the enum, but I'd thought someone
would have added a warning for this:
#include <stdio.h>
enum { A, B } foo = A;
enum { C, D } bar = C;
int main(void)
{
switch (foo) {
case C:
puts("A");
break;
case B:
puts("B");
break;
}
}
But none of the 4 C compilers (gcc, clang, suncc & xlc) I have warn
about it. Good to know.
