I think something like this would be better imo; I don’t like ‘cannot’ since we
still accept the code, so it’s not technically correct that it *cannot* have a
linkage specification (it can’t according to the standard, but only EDG
currently diagnoses this, and even then it’s just a warning), it just really
*shouldn’t*.
