Issue 4646: distutils chokes on empty options arg in the setup function (original) (raw)

Distutils setup function accepts an 'options' named argument which allows to pass options to subcommands in a dictionary (At the moment I cannot find where this is documented). When an empty dictionary is passed, distutils spits out a warning:
