How do you distinguish Solaris 5.10 and Solaris 51.0?

Maybe multiply the major version by 100 or 1000? or use a shift of 8 bits? The usage would be:

major = VERSION >> 8
minor = VERSION & 255

The disavantage is the need to write versions in hexadecimal :-(

@erlend-aasland: Should we prefix new pyconfig.h constants by Py_ ? see: capi-workgroup/problems#46

I think we should follow the PEP-7 recommendations: https://peps.python.org/pep-0007/#naming-conventions

How do you distinguish Solaris 5.10 and Solaris 51.0?

I see what you mean, but that's not happening. The leading 5 was dropped from the name 25 years ago and while e.g. uname and compilation targets still use it, nobody today calls it Solaris/SunOS 5.10; only Solaris 10. If we ever release Solaris 51, uname -r should report it as 5.51.

That said, I am not strongly against changing it if you still prefer your suggestion.

Thanks, I missed that. It's fixed now.
