Well, that's not surprising - if the function is not in CONTAINS
(internal/module procedure) or in a module, the prototype is not available in
Fortran thus it is just an external procedure without any known interface (even
if it is just one line higher up).

One purpose of -fwhole-file is to allow to diagnose such things as error.

I think this is fixed by the following patch. If I understand the code
correctly, we currently only append the void_type_node if there is at least one
argument, which allows for "(...)" for procedures without any argument.
