After some investigation I discovered the folling:
(please correct any mistake - I know my knowlegde is very basic and
darwin seems to be not so good documented at all, addtionally I'am new
to POSIX pthreads.)
a) The library which must be used for linking is the default library
(tried that with a small app)
b) The threads are created in the JOINABLE state per default
c) A thread which is in the exit state cannot be detached (only joinable
So the current configure script must fail ("test for linking with the
default libraries") because the test spawn a thread (this is ok) then
the main routine sleeps a second. In the meantime the thread dies
because there are no statements to execute and the thread will be
terminated (implicit call to pthread_exit(). The thread is now in the
By changing the execution order (putting the sleep AFTER the detach
call) the test will function because pthread_detach will see an living
thread which is JOINABLE and can be detached (I did that and the test is
running with exit code 0, without the change, the test will exit with
rc=22 and configure will fail)
Any comments available? May be from a serious darwin developer? (I only
have the sources of darwin 1.0, maybe that changed to 1.2 - this is the
current version of MacOS X Retail).

Well... I do not think, that a fix (even if I ever could apply one)
would be a great help...
