I looked at that.  The line that does the tests is in
config/acx_pthread.m4:

    acx_pthread_flags="pthreads none -Kthread -kthread lthread -pthread
    -pthreads -mthreads pthread --thread-safe -mt pthread-conf ig"

so you should see that list tried.  Does that help?

I am majorly concerned that Slackware has the same problem as Unixware,
meaning that if you use threading in the lib, you now need the flags on
every applicaiton that uses the lib.
