[elephant-devel] Elephant is working with cffi

[Gustavo]

Hello, again,

I've realized that elephant-1.0 is actually newer than elephant-unstable. I
made a few more changes and updated the patch to work with elephant-1.0.

The configuration was tested without the feature :elephant-without-optimize
and all tests from elephant test suite passed.

Gustavo.
