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
