We don't seem to document when features were introduced, so I don't see the
point in this (do we expect clients to go searching through our version
control history?). In practice, ./configure scripts and CMake use "does
this function exist" checks to directly test the existence of the function
(maybe you were talking about doing this purely inside an #ifdef in the
source code?).
