[bug #24111] NetBSD Unable to detach thread

[Sebastian Reitenbach]

Follow-up Comment #11, bug #24111 (project gnustep):

On OpenBSD i seem to have the same problem, usually -lpthread is used.

I checked the system libobjc, a ldd only shows me this:

ldd /usr/lib/libobjc.so.4.0
/usr/lib/libobjc.so.4.0:
        Start    End      Type Open Ref GrpRef Name
        0e4d9000 2e4df000 dlib 1    0   0      /usr/lib/libobjc.so.4.0

but I find pthread related symbols in it:
# nm libobjc.so.4.0  | grep -i thre

         U pthread_mutex_trylock
         U pthread_mutex_unlock
         U pthread_self
         U pthread_setspecific

so I guess it should support threading.
