That is a different issue and really should be filed in a different bug.  The
issue there is C++'s enums are only defined for those two values.

one more valid code rejected by 4.1/4.2:

typedef enum { foo, bar } e;
int zoo( e __e )
{
switch ( __e )
{
case foo: return -1;
case bar: return +1;
}
}

$ x86_64-gnu-linux-g++ bug.cpp -c -Wall -O2
bug.cpp: In function 'int zoo(e)':
bug.cpp:9: warning: control reaches end of non-void function
