Make the Distribution() constructor forgiving of unknown keyword
arguments, triggering a warning instead of raising an exception. (In
1.5.2/2.0, it will print to stderr.)
Bugfix candidate for all previous versions. This changes behaviour,
but the old behaviour wasn't very useful. If Distutils version X+1
adds a new keyword argument, using the new keyword means your setup.py
file won't work with Distutils version X any more.
