BUG: configure fails testing -pthread on FreeBSD

The linuxthreads package is not usually installed on FreeBSD.
There is no reason why it should be. FreeBSD-6.1 has two native implementations of POSIX
threads installed by default. Nobody in their right mind should be expected to install a third
one.

The current configure seems to test only for linuxthreads which definitely is not the way to
test for POSIX threads anywhere else but Linux. Even for linux that is far less generic than
it needs to be.

Use $CC -pthread for FreeBSD.

Follow up

motion search the "standard" location of linuxthreads in freebsd AFIAK is always the same, maybe i'm wrong but nobody complained about it. Moreover if linuxthread libs / headers are installed outside the common path the compile won't find them ... so what will be a nice solution then ?

Argh... Maybe I was not expressing myself properly. What I tried to say is that FreeBSD thread library is not necessarily the linuxthreads library.

At least all FreeBSD 6.x versions have a couple of different perfectly OK thread libraries which have nothing to do with linuxthreads. There is no sane reason though why Motion should not work just fine with native threads on FreeBSD. (I guess this should apply to FreeBSD 5.x as well, but I cannot really tell for sure, because I upgraded directly from 4.11 to 6.1.

Jukka , I made the port to FreeBSD making as simple as possible , so i used pthread ... i know that is a bit annoying to install linuxthread but at the moment i have no time to make a better port.

I've tested motion-3.2.7 svn 111 with native pthread on FreeBSD and seems pretty stable so i gonna change it in configure.in to use by default native pthread and allow use linuxthreads as a option. That will allow people to use native pthread on FreeBSD > 5.4 or linuxthreads for olders versions. I'll post the information about the svn version that contains that fix.
