  New Revision: 28507

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=28507

  Log:
    * thread_pthread.c (thread_start_func_1): don't call
      native_thread_init_stack(th) on cygwin to avoid the segv
      introduced by r27789. Cygwin's signal implementation is half
      baked so USE_SIGNALSTACK is not defined and it needs another
      treatment.
