gcc 8 has added a new warning heuristic to detect invalid function casts and
a stock python build seems to hit that warning quite often.  The most common
is the cast of a METH_NOARGS function (that uses just one argument) to a
PyCFunction. Fix this by adding a dummy argument to all functions that
implement METH_NOARGS.
bpo-33012: Fix invalid function cast warnings with gcc 8 for METH_NOARGS. (GH-6030) METH_NOARGS functions need only a single argument but they are cast into a PyCFunction, which takes two arguments. This triggers an invalid function cast warning in gcc8 due to the argument mismatch. Fix this by adding a dummy unused argument. 2018-04-29 15:59:33 -03:00			`gcc 8 has added a new warning heuristic to detect invalid function casts and`
