But isn't this last case exactly the scenario that Florian mentions they have in the glibc build issue? Meaning they have a gcc that defaults to -mlong-double-128 and they're building individual files using -mlong-double-64 -mabi=ibmlongdouble which you state should not be ok, but as it stands now, it's already not ok and that is what is causing the build to error out. Or am I misunderstanding you?
