   Hmmm.  At first I was going to say use autoconf for this, but it
   seems to me that this is really a target issue, so autoconf doesn't
   help.

   Similarly for my comment about the gbl-ctors.h change in my last
   message.

   So I'm not sure what to do.

I think the second extern should be blown away.  If the defines say "I
HAVE_ATEXIT" and "I do not NEED_ATEXIT" the extern should not be
there.  Else the meaning of these macros should be clarified.
