There's no attempt by GCC maintainers to make a newer compiler work with the older libstdc++ versions. They probably work, considering that the old library probably doesn't use any intrinsics and such the newer compiler doesn't have (modulo things that have been removed for one reason or another), but bug reports for such combinations are likely going to be outright rejected as invalid. For example, if there's some code in an old libstdc++ that the newer compiler doesn't accept, there's going to be exactly zero effort to fix that. _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
