Note: MODULE PROCEDURE and PROCEDURE mean different things.

"MODULE PROCEDURE" can only be a procedure which is a procedure from that
module. "PROCEDURE" can be any procedure whose interface is explicitly known:
Module procedures, use-associated procedures, external procedures (via
INTERFACE or PROCEDURE(...) statement).

I think this implies another bug as I believe there is not any module procedure
in that module. Using "MODULE PROCEDURE" other compilers give also an error:

NAG f95:
Error: af.f90, line 11: Undefined module procedure X

g95:
Error: EXTERNAL-PROC procedure 'x' at (1) is already a MODULE-PROC procedure

I will try your pr33162 patch. (Might take a while since I have at the moment
only a lousy internet connection.)
