+*Revision History:
+*	06-02-89   PHG	module created
+*	03-14-90   GJF	Made calling type _CALLTYPE1 and added #include
+*			<cruntime.h>. Also, fixed the copyright.

+*div_t div(int numer, int denom) - do signed divide
+*
+*Purpose:
+*	This routine does an divide and returns the results.
+*	Since we don't know how the Intel 860 does division, we'd
+*	better make sure that we have done it right.
+*
+*Entry:
+*	int numer - Numerator passed in on stack
+*	int denom - Denominator passed in on stack
+*
+*Exit:
+*	returns quotient and remainder in structure
+*
+*Exceptions:
+*	No validation is done on [denom]* thus, if [denom] is 0,
+*	this routine will trap.
