I would not say it is a bug, but rather a consequence of the
implementation of pyximport.
Likely a call to "dist.parse_config_files()" should be added just
before "dist.parse_command_line()" in pyximport/pyxbuild.py
However, if you do this, a "setup.cfg" file will be parse if present
in $PWD... This could be seen as a gotcha, or as a feature...
