I intend to merge this, push a 0.4.0 tag and then push the wheels and sdist to PyPI.

I've just pushed this to PyPI but when I downloaded the wheel on Linux it crashed:

$ python test/test.py 
test_pyflint...OK
Illegal instruction (core dumped)

On OSX all tests and doctests passed. I'm going to test Windows now...

Windows is fine as well. So the problem is just Linux. (The one thing I didn't test!)

I've deleted the Linux wheels from PyPI. Now someone using pip install python-flint on Linux goes back to building from source as before.

Further investigation needed but it's late and I need to go to bed.
