--- Comment #3 from Matt Jacobson <mhjacobson at me dot com> --- Thanks -- I updated to 10.3.0 and looked into the changes. (Sorry for originally filing this against such an out-of-date compiler.) As it happens, I'm targeting the NeXT v2 runtime, but I'm *not* actually targeting Darwin. So `flag_next_runtime` is just 1 for me--not an OS version value like 100600 (`USE_FIXUP_BEFORE` / SnowLeopard). (And I can't fake it via arguments, AFAICT.) I wonder if it would be reasonable to add a separate flag to disable (or enable) fixup messages, such that the default value of the flag is controlled by `-mmacosx-version-min` when targeting Darwin.
