* 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.
PR fortran/25785
* resolve.c (resolve_function): Exclude PRESENT from assumed size
argument checking. Replace strcmp's with comparisons with generic
codes.
