Steve,

I tried this as follows:

enum BODY { SUN, MOON, STAR } ;
enum PLANET { EARTH, VENUS, MARS, PLUTO } ;
int main ( void )
{
  BODY body ;
  body = static_cast < BODY > ( 3 ) ; // does not give error.
  body = static_cast < BODY > ( PLUTO ) ; // does not give error.
}

but it still does not throw an error even though the enum being casted 
*to* does not contain an identifier equivalent to the value actually 
being casted, whether a primitive integer or an identifier belonging to 
another enum.

Don't you think this is a GCC bug?
