This means, I think, that your WinMain is not prototyped/defined
"properly". It should look like this:

int STDCALL
WinMain (HINSTANCE hInst, HINSTANCE hPrev, LPSTR szCmd, int nShow)

Especially important is the STDCALL (WINAPI will also do I think)
which gets that @16 tacked onto the end of the function name
and makes it have the proper calling convention.

If that's not the problem then I'm afraid I don't know what's wrong.

Colin.
