[Bug fortran/31473] gfortran does not detect duplicate EXTERNAL or INTRINSIC declarations

["burnus at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #1 from burnus at gcc dot gnu dot org  2007-04-04 18:57 -------
Confirmed. Thanks for the report.

gfc_add_external and  gfc_add_intrinsic do actually the right thing. However,
they are not used in decl.c's gfc_match_external:

  gfc_clear_attr (&current_attr);
  current_attr.external = 1;

I don't think it makes sense to delete all previously defined attributes.
This also allows for
  intrinsic foo
  external  foo

Ditto for gfc_match_intrinsic.

I think there might be a reason for clearing the attributes, even though I
cannot think of one right now.
