* gfortran.h: Prototype for gfc_add_in_equivalence.
* match.c (gfc_match_equivalence): Make a structure component
an explicit,rather than a syntax, error in an equivalence
group. Call gfc_add_in_equivalence to add the constraints
imposed in check_conflict.
* resolve.c (resolve_symbol): Add constraints: No public
structures with private-type components and no public
procedures with private-type dummy arguments.
(resolve_equivalence_derived): Add constraint that prevents
a structure equivalence member from having a default
initializer.
(sequence_type): New static function to determine whether an
object is default numeric, default character, non-default
or mixed sequence. Add corresponding enum typespec.
(resolve_equivalence): Add constraints to equivalence groups
or their members: No more than one initialized member and
that different types are not equivalenced for std=f95. All
the simple constraints have been moved to check_conflict.
* symbol.c (check_conflict): Simple equivalence constraints
added, including those removed from resolve_symbol.
(gfc_add_in_equivalence): New function to interface calls
match_equivalence to check_conflict.
