Are undeclared (auto-generated) copy constructors automatically marked as inline?
If so, and if I don't want them to be marked as inline, does that mean I have to define one manually and copy every single member I need by hand (assuming I'm not using C++11, so that there's no = default to take advantage of)?
They're treated as if they were declared inline (which doesn't
necessarily mean that they will be inlined). And yes, in
pre-C++11, the only way to prevent their being inline was to
declare and define them manually, copying every member and every
base class explicitly in the initializer list.
