        * match.c (gfc_match_associate): Before failing the association
        try again, allowing a proc pointer selector.

        * primary.c (gfc_match_varspec): Introduce 'tgt_expr', which
        points to the associate selector, if any. Go through selector
        references, after resolution for variables, to catch any full
        or section array references. If a class associate name does
        not have the same declared type as the selector, resolve the
        selector and copy the declared type to the associate name.
        Before throwing a no implicit type error, resolve all allowed
        selector expressions, and copy the resulting typespec.

        PR fortran/67543
        * resolve.c (resolve_assoc_var): Selector must cannot be the
        NULL expression and it must have a type.

        PR fortran/78152
        * resolve.c (resolve_symbol): Allow associate names to be
        coarrays.
