 *	Apollo Changes:
 *
 *	08/11/89 rps		matherr decls from system V
 *      01/07/89 mills      Add asinh,acosh,atanh,copysign,drem,logb,scalb, and cabs
 *                          note no prototype checking for cabs()
 *      03/23/88 lwa        Fix incorrect fabs() decl.
 *	12/04/87 james_w	Provide function prototypes.
