I think that's fine.  In real code, presumably some other file will 
provide the enumerator list for V, and otherwise treating it as 
incomplete is a good enough approximation; an opaque enum declaration is 
not a definition even though the type is considered complete in the C++ 
sense.

If one file has the enumerator list and another doesn't, does GDB handle 
that properly with DWARF output (making the list available while 
debugging code from the file that doesn't have the list)?

Right; earlier I was suggesting to change ENUM_HAS_VALUE_LIST_P to be a 
language-independent macro, something like "ENUM_LACKS_VALUE_LIST".
