wsprintf(char *string, char *format, ...) is a vararg function in the
Windows API, and it uses the __cdecl calling convention.  I guess that's why
they support multiple calling conventions; you choose whatever is needed to
satisfy your requirements.  __stdcall saves an instruction per call, so I
guess it makes sense to use it whenever possible; but you're right, __cdecl
is necessary for variable arguments, so it's good to have around.
