+; This signed-division function returns both the quotient and the remainder,
+; in this structure:
+;
+; typedef struct {
+;     int rem, quot;
+; } div_t;
+;
+; div_t __fastcall__ div (int numer, int denom);
+;
+; Both sides of an assignment-expression must be cast to (long)
+; because cc65 functions can't return structures -- yet.  Example:
+;
+; #include <stdlib.h>
+; div_t answer;
+;
+; (long)answer = (long)div(-41, +3);
+; printf("The quotient is %d, and the remainder is %d.\n",
+;	answer.quot, answer.rem);
