Hi,

is there a macro that can be tested to know if a compiler doesn't support classes with constructors in unions?

What compiler(s) implement this as an extension? It isn't allowed in C++03 either: "An object of a class with a non-trivial constructor, a non-trivial copy constructor, a non-trivial destructor, or a non-trivial copy assignment operator cannot be a member of a union, nor can an array of such objects." -- Nevin ":-)" Liber <mailto:nevin@eviloverlord.com> (847) 691-1404
