Hi there.
Lets say, i have foo.pyx. and use cythonize() to generate foo.c.
Calling cythonize() a second time will correctly do nothing, because

foo.c now looks different. But: Deleting f

If someone tells me, how to fix distutils, (better: does it), i might
change my mind. also, I need VPATH... just something
