It is now only possible to prescribe options for subprocesses (e.g. build_ext) in the file setup.cfg But some of these options are obligatory to get the correct result for the action. These options can be set in the file setup.cfg, but it is not clear that these options should not be changed, nor is it clear in the setup.py file that the setup.cfg is relevant. I tend now to not to use the setup.cfg and call 'python setup.py' (without arguments). The setup.py will then fill in the necessary options in sys.argv . It would be much nicer if these options could be explicitly given as defaults for the subprocess.

I am not developing Python extensions anymore, so I am not interested in this issue. I am not sure whether this issue is still applicable to e.g. Python 3.0 You can close it if you wisj
