Well, as someone who recently added FreeBSD to the list of supported platforms for an open source application, I won't begin to go through the pain and heartache that I had to endure to a) understand and b) work around the way FreeBSD does threads. GNU automake, autoconf and to some extent, gcc, all don't like the way that we do this. I would rather see us change to the "GNU standard" of doing this, especially since it would eliminate one more strangness that surrounds FreeBSD. After all, we're going to have to do it eventually -- now's just as good a time as any! -- Matt Emmerton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
