Norma, what that call does is set the behaviour on exit of the newly
created thread. I can (and will) whip up an implementation of this in
cygwin1.dll for the future.

For now I suggest you use

int
gp_create_thread(gp_thread_creation_callback_t proc, void *proc_data)
{
    gp_thread_creation_closure_t *closure =
(gp_thread_creation_closure_t *)malloc(sizeof(*closure));
    pthread_t ignore_thread;
    pthread_attr_t attr;
    int code;

    if (!closure)
return_error(gs_error_VMerror);
    closure->proc = proc;
   closure->proc_data = proc_data;
    pthread_attr_init(&attr);

/* this should be a feature test, not a platform test - do you have
autoconf ? */
#ifndef __CYGWIN__
    pthread_attr_setdetachstate(&attr, PTHREAD_CREATE_DETACHED);
#endif
    code = pthread_create(&ignore_thread, &attr,
gp_thread_begin_wrapper,
  closure);
    if (code) {
free(closure);
return_error(gs_error_ioerror);
    }
/* reverse of previous test */
#ifdef __CYGWIN__
  pthread_detach(ignore_thread);
#endif
    return 0;
}

which will have the same behaviour.

Rob
