(j3.2006) Binding label consistency in module procedures

[Lionel, Steve]

And how did I miss this?

C1250 (R1225) If MODULE appears in the prefix of a module subprogram and a
binding label is specified, it shall be the same as the binding label
specified in the corresponding separate interface body.

Isn't this already prohibited by the last sentence of 16.2 p1:

"An entity of the program shall not be identified by more than one binding
label."

Cheers,

characteristics shall be consistent with those specified in the procedure
definition.". However, the list of procedure characteristics (12.3.1)
includes only "whether it has the BIND attribute" and not the value of NAME=
in a language-binding-spec.

because of the name mismatch. Thoughts?
