It is clear to me that this is standard-conforming. The binding label is 
required to be a default-char-constant-expression, and c_name, visible 
in the interface block through the import, is exactly that. If there is 
some additional restriction on the NAME= value that prohibits this, I 
can't find it.

As a former developer, though, I can understand how this sort of thing 
happens.
