The patch is https://src.fedoraproject.org/fork/churchyard/rpms/automake/raw/f8af40fe1fa92a3ea0a1520a9d5f0797d0019f0f/f/automake-1.16.2-python-version-multiple-digits.patch
Thanks, I pushed it with some minor additional documentation updates. python3.10 -c 'import sys; print("%u.%u" % sys.version_info[:2])' I also changed the invocation in python.m4 to be this (what you put in t/python-vars.sh), instead of the sys.stdout.write('%d.%d') which you had (following what was there before). Seemed better to have the two invocations be exactly the same. At least, I couldn't discern any reason why not, or any difference in the result, barring version numbers too big to fit in signed integers :). --thanks, karl.
