--- Comment #11 from Iain Sandoe <iains at gcc dot gnu.org> --- unfortunaely, not quite (yet) complete. I tried 217505 + c#10 - on x86_64-darwin12 all langs bootstrap proceeds up to the build of Ada lib. I reverted r217292 and re-tried - bootstrap passed, so still some gremlin remains (i'll be glad to try to analyse, but no cycles until the weekend). Also thanks for doing this work! Clang compatibility is a _very_ useful thing on Darwin.
