Should be able to run "python setup.py install" without a C compiler

[James Henstridge]

Storm's C extension provides optional functionality, so it isn't strictly necessary to compile it. However, the distutils setup.py script will bail out if no C compiler is available (or an incompatible C compiler).

It would be nice if the setup.py script could automatically omit the C extension if a compiler is not available.

One possible implementation is that found in zope.interface:

    http://svn.zope.org/zope.interface/trunk/setup.py?view=auto

That one eats legitimate compile errors though, which would be good to avoid.
