*Revision History:

*	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.
