Re: Autotools macro to test for pthreads fails with "Resource lost" on hurd

Hello!

First: thanks for reporting this!

This can indeed be reproduce independently:

    thomas@dirichlet:~ $ cat p.c
    #include <pthread.h>
    int
    main(void)
    {
      pthread_kill(pthread_self(), 0);
    }
    thomas@dirichlet:~ $ uname -a
    Linux dirichlet 2.6.31-5-generic #24-Ubuntu SMP Sat Aug 1 12:48:18 UTC 2009 i686 GNU/Linux
    thomas@dirichlet:~ $ gcc p.c -lpthread
    thomas@dirichlet:~ $ ./a.out 
    thomas@dirichlet:~ $ echo $?
    0

    tschwinge@flubber:~ $ uname -a
    GNU flubber 0.3 GNU-Mach 1.3.99/Hurd-0.3 i386-AT386 GNU
    tschwinge@flubber:~ $ gcc p.c -lpthread
    tschwinge@flubber:~ $ ./a.out 
    Resource lost
    tschwinge@flubber:~ $ echo $?
    160

So this is either something invalid to do (I didn't check yet), or it is
a bug in our libpthread.  Stay tuned.


Regards,
 Thomas
