  New Revision: 46278


    * thread.c (rb_thread_atfork_internal): My compiler complains
      about this variable being used before initialized. I looked at
      the code and expanded the macro and turned out it was actually
      USED for pointer arithmetic, not dereferenced.  So this was
      never a serious bug.  But is annoying indeed to see warnings
      every time.  I added `=0` and all went healthy.
    * configure.in: Also, I found that the problematic macro expansion
      only happens when we lack __typeof__ C extension, which shall
      not be the case of my compiler.  I added AC_CTYPEOF to kick ass.
