    c++: parenthesized -> resolving to static data member [PR98283]

    Here we're neglecting to propagate parenthesized-ness when the
    member access (this->m) resolves to a static data member (and
    thus finish_class_member_access_expr yields a VAR_DECL instead
    of a COMPONENT_REF).

            PR c++/98283

    gcc/cp/ChangeLog:

            * pt.cc (tsubst_copy_and_build) <case COMPONENT_REF>: Propagate
            REF_PARENTHESIZED_P more generally via force_paren_expr.
            * semantics.cc (force_paren_expr): Document default argument.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp1y/paren6.C: New test.
