enum foo { FOO, BAR };

/* Even though the underlying type of an enum is unspecified, the type
   of enumeration constants is explicitly defined as int (6.4.4.3/2 in
   the C99 Standard).  Therefore, `i' must not be promoted to
   `unsigned' in the comparison below; we must exit the loop when it
   becomes negative. */
