At the moment I do this

find /usr/include/ -type f -and -name -not "pyconfig.h" -delete
find /usr/include/ -type d -empty -delete

instead of a simple "rm -r /usr/include/".

However the question is whether or not Arch should move the file
to /usr/lib/python2.7/. As said before, my understanding is that files with
configuration data used for runtime should not live in /usr/include/.
