        * symbol.c (check_conflict): Add pointer valued elemental
        functions and internal procedures with the external attribute
        to the list of conflicts.
        (gfc_add_attribute): New catch-all function to perform the
        checking of symbol attributes for attribute declaration
        statements.
        * decl.c (attr_decl1): Call gfc_add_attribute for each of -
        (gfc_match_external, gfc_match_intent, gfc_match_intrinsic,
        gfc_match_pointer, gfc_match_dimension, gfc_match_target):
        Remove spurious calls to checks in symbol.c.  Set the
        attribute directly and use the call to attr_decl() for
        checking.
        * gfortran.h:  Add prototype for gfc_add_attribute.

        * resolve.c (resolve_function): Exclude PRESENT from assumed size
        argument checking. Replace strcmp's with comparisons with generic
        codes.
