We're talking about something we'd ask authors of packages that weren't written for FreeBSD to include (and to include for NetBSD and OpenBSD) to get their packages to work with ours. This isn't just for your own ports use. Since just including sys/param.h would cause packages to fail to compile on many platforms, no one outside FreeBSD would be willing to take our advice on it. We need something that works for Free|Net|OpenBSD but isn't fatal for other platforms. > > Bruce > ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 9120 Edmonston Ct #302 | Greenbelt, MD 20770 | I run Journey2 and picnic, both FreeBSD (301) 220-2114 | version 3.0 current -- and great FUN! ----------------------------+-----------------------------------------------
