 -	SEGMENT()
 -
 *	Purpose:
 *		This macro allows us to control whether code_seg()s get defined
 *		in a source module or not.  Currently, these are only defined on
 *		the Win16 platform.  On Windows 95 and NT this macro expands out to
 *		a #pragma comment(). The usage in a source module is:
 *
 *			#pragma SEGMENT(segment_name)
 *
 *			For Lego, the code_seg should never be used - TF
