+Subject: [PATCH] Parenthesize Py<type>_Check() in ifs
+
+In C, if expressions should be parenthesized.
+PyLong_Check, PyUnicode_Check etc. happened to expand to a parenthesized
+expression before, but that's not API to rely on.
+
+Since Python 3.9.0a4 it needs to be parenthesized explicitly.
+
+Fixes https://gitlab.gnome.org/GNOME/libxml2/issues/149
+Upstream-Status: Backport
