- Subject: How to get unused variable warning for non-PODs
I want to know if its possible to get warnings for unused variables that have a user defined constructor and/or destructor.
I know that they are side-effect free and want to mark them for the compiler. But neither attribute const nor pure helped me here.
Btw: std::string would be IMO a good candidate for such an attribute.
Any ideas how to achieve this with GCC 3.4.x?
