Good joke. ;)

No. There are workarounds like in http://stackoverflow.com/questions/225432/export-all-symbols-when-creating-a-dll but it's too much work.
Basically you want to define a macro that resolves to __declspec(dllexport) when building the DLL and to nothing when only using libraries headers.

Visual Studio doesn't work like a good gcc? Because, I try this code with mingw (32 and 64) and it's working perfectly.
Is there some option to export automatically some methods without using __declspec(dllexport)?
