I believe the file in include/ should also have the exception text.  The
question to ask is: might a plugin want to include this file?  If yes,
it should have the exception text.

That would not work reliably in C++ since it would be out of range of
the other enum values.

That would be fine.

This is OK for gcc if you use the exception text in the license.

Thanks.
