+Subject: [PATCH 1/2] xcbgen: Use math.gcd() for Python >= 3.5.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+fractions.gcd() has been deprecated since Python 3.5, and
+was finally dropped in Python 3.9.  It is recommended to
+use math.gcd() instead.
