Just taking a look at this again.

There are two points where an error could be issued.
First,

INTEGER X, Y, SUBA
EXTERNAL SUBA

clashes with

SUBROUTINE SUBA(X)

so we could flag this going through the global list
of symbols.

Second,

  EXTERNAL SUBA
  CALL ANY (FNC, X, Y)
  INTEGER FNC

should also clash with

  SUBROUTINE SUBA(X)

but that is much harder, because we would then have to check
for the argument that is passed to ANY.

This is not caught by ifort or PGI fortran either. Nagfor, however, gets it.

Still no error issues, not even with -flto.

Not powerpc-specific.

Confirmed, but minor since a lot of the other fortran implemenations don't
detect it either.
