Bug in 4.3 C

[Tomas Rokicki]

[ `---\-  For the plane eater ]

/*
 *   This program should print out:
 *   -1 0
 *   because the subtraction should be done with signed
 *   arithmetic; it did under 4.2 bsd on a VAX.  Now,
 *   however, under 4.3 bsd, it prints out
 *
 *   -1 1
 *
 *   Anyone know to whom I should post this bug?
