I've never done Windows programming but AFAICT you don't use `int main()` on Win32 anyway, you write something like

  int WINAPI WinMain(HINSTANCE hInst, HINSTANCE hPrevInst, LPSTR, int)

(where WINAPI is just a macro for __stdcall)

I also found a reference saying you can in fact use `int main()` if you want to, in a GUI subsystem Windows app, by using the Microsoft linker options /subsystem:windows /ENTRY:mainCRTStartup, but in that case you're not writing a stdcall function anymore.

EDIT: I guess I should clarify, my previous comment was talking about cdecl functions, i.e. the default calling convention in C.
