In progress.  Two comments:

* Why the fixincl.tpl change?  Is this necessary with upstream autogen
  or only due to some Ubuntu-local change?  Bruce will probably know
  when he reviews the patch, though.

* Your comment

 /*
  *  Before Mac OS X 10.7 <i386/setjmp.h> doesn't mark longjump noreturn.
  */

  is wrong, however: even the 10.7 <i386/setjmp.h> does lack the
  annotation, and in 10.8 (as I'd seen in 10.11 and 10.12) the
  declaration has moved to <setjmp.h> and is properly annotated.  I
  suspect the bypass can just go, even if it does no harm.

  You can find the 10.8 <setjmp.h> at

        http://opensource.apple.com/source/Libc/Libc-825.24/include/setjmp.h

  while the 10.7.5 one (the latest 10.7 update) is at

        http://opensource.apple.com/source/Libc/Libc-763.13/include/setjmp.h

  and the corresponding <i386/setjmp.h> at

        http://opensource.apple.com/source/xnu/xnu-1699.32.7/bsd/i386/setjmp.h
