sizeof(long) in 64-bit C++

Question

I have downloaded MinGW-64, so I can now compile 64-bit programs for Windows 7, using g++ 4.7.0 (experimental). But the following line:

cout << sizeof(         


        

Answer 1

Most of Windows applications are written with the expectation that for all intents and purposes int=long=32 bits. I'm guessing MinGW is just making sure it's still the case and there're no surprises.
