--- Comment #8 from Iain Sandoe <iains at gcc dot gnu.org> 2011-02-08 12:17:28 UTC ---
what was the reason that the patch at comment #1 was not acceptable?

If the builtins were not available prior to 4.0.5, then the caveat seems
sensible ... I must be missing something ;)

===

if not, for all darwin 8 & 9 the system compiler is 4.0.1 
(3.3 for darwin 7, and I doubt trunk builds for earlier than that)

4.2.1 is not available on darwin 8 (so I'd imagine that bootstrap is broken
there without a ready workaround).  I don't have a ppc darwin 8 box available
right now - although I will try to crank one up before 4.6 forks.

I could not find a permutation of installed headers that gave the right result
- perhaps looking in the wrong place.

Do we want to pursue this further - or just accept a slower solution for the
(legacy) darwin versions?
