Bootstrap fails in libstdc++ with the following error. I haven't investigated it much except to take a peek at recent libstdc++ commits where r261525 looks like it introduced __glibcxx_check_can_increment_range, so it seems like it might have something to do with it. I don't see a __glibcxx_requires_can_increment_range macro defined anywhere in the patch so maybe it's a typo? Francois, can you please see what's going on?

__glibcxx_requires_can_increment_range(__first, __last, __result); Thanks Martin
