It's meant to detect changes that can break existing binary modules.
In most cases, this would be changed structs.
Whether such changes happened between 2.3 and 2.4, I don't know.

If you want to ask whether a certain function is present, either use
autoconf, or check for the Python (hex) version where it was first
introduced.
