[issue34143] There is a constant definition error in errno.py

[Ronald Oussoren]

I’m not sure if I understand correctly. Is your report about the difference in 
the values of EAGAIN between Linux and macOS?

If so, that is not a bug: the relevant standards only document the name and 
type of these constants and not their values. The value can and does vary 
across operating systems.
