Summary: CV-qualified base class erroneously forbidden Product: gcc Version: 4.6.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: pot...@mac.com DR 484 (http://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#484) modifies §9.1/5, which allows a typedef-name to be used as a base class specifier, to specifically say that cv-qualification of such a typedef is ignored. GCC issues an error "base class ‘t’ has cv qualifiers". This should be a warning, if anything. Even without the DR, the standard was previously silent about this, so rejecting the code outright is a radical approach.
