+Subject: [PATCH] Fix test_is_compatible to fix Python 3.10 support
+
+On Python 3.10, PYVER is py310 which wrongly matches the original
+'py27' <= PYVER < 'py32' condition.  Replace it with explicit match
+against known Python versions in this range.  This is probably
+the simplest and the most future-proof solution to the problem at hand.
