Right, the equivalent for NetBSD vfprintf.c is: revision 1.40 date: 2001/11/28 11:58:22; author: kleink; state: Exp; lines: +4 -4 Since we're returned the sign of a floating-point number by __dtoa(), use that to decide whether to include a minus sign in the result. Fixes printing -0.0, and thus PR lib/3137. NetBSD 1.5 has revision 1.32, NetBSD 1.6 has revision 1.42 Well spotted, Patrick ---------------------------(end of broadcast)--------------------------- TIP 2: you can get off all lists at once with the unregister command (send "unregister YourEmailAddressHere" to [EMAIL PROTECTED])
