One way to do that would be like so:

	#include <dos.h>

	if (_get_dos_version (1) == 0x0532)
	   /* we run in NT DOS box */
	else
	   /* some other environment */

My references indicate that DOS box on NT always returns version 5.50
(0532h) when you call DOS function 3306h (which is what `_get_dos_version'
does when called with a non-zero argument, see the libc docs).  Can people
who work on NT please see if that's true for both 3.5x and 4.0?
