I disagree. it is the set of supported compiler/platform that define the set of feature we can or cannot use without #ifdef > For example, suppose we want to allow template-template parameters > in the code without restrictions.

Once we allow a > feature unrestrictedly and it enters the API, there's no going back. In that case, #ifdef are going to be added around that kind of API that cannot be used with that compiler. This is one reason rvct did not have QtConcurrent. _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
