+
+ 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
