Yes.  I tested it with -mwindows -mno-cygwin.  I couldn't print to the
console in that case so I ran it under the debugger.

I copied the WinMain from setup.exe into a test program.

cgf

#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

int WINAPI
WinMain (HINSTANCE h,
	 HINSTANCE hPrevInstance,
	 LPSTR command_line,
	 int cmd_show)
{
  char **argv;
  int i;
  for (i = 0, argv = __argv; *argv; argv++)
    printf ("%d - '%s'\n", i, *argv);
}
