Actually, this is not true.  Even in a true win32 app, argc and argv are
available, they are just not as obvious. The following program will print
the location of the exe.

---------------------------------------------------------------------------
#include "stdafx.h"
#include "stdlib.h"  // for __argc and __argv
#include "stdio.h"  // for sprintf

int APIENTRY WinMain(HINSTANCE hInstance,
                     HINSTANCE hPrevInstance,
                     LPSTR     lpCmdLine,
                     int       nCmdShow)
{
	char msg[300];

	sprintf(msg, "%d args.  Arg0 is %s", __argc, __argv[0]);
	MessageBox(NULL, msg, "argv test", MB_OK);

	return 0;
}
