If the interface in a PROCEDURE() statement is Bind(C), also the

From the F2008 standard: "A proc-language-binding-spec without a NAME=
is allowed, but is redundant with the proc-interface required by C1222."
Build and currently regtested on x86-64-linux.
OK for the trunk (if regtesting succeeded)?
Well, it didn't as I forgot to reset two variables - one then gets then
an error that one has specified an binding name - or the wrong binding
name might be used.

OK?
