$NetBSD: patch-ae,v 1.5 2014/09/22 11:56:39 joerg Exp $

- avoid union wait
- force termios on all modern systems
- declare void functions void
- avoid implicit int
- don't declare own errno
- fix os conditionals (apparently with respect to VMS)
- call execl() and execlp() correctly
- don't synthesize vsprintf with fake arguments
- use ctype.h functions correctly
