It would also allow using builtins in installed headers more easily, e.g. for
isnan, isfinite abstractions without the need of juggling version number
checks.
This simplifies work for stacks of software deriving from one common base
library. The deriving applications could use the efficient builtins via the
common base header instead of each having to add their own checks.
Similarly useful would be the related __has_attribute, those especially tend to
cause a huge mess of version number checks.
