Hi,

In working on the Debian package, I found that the ffi ruby library
embeds an entire code-copy of the upstream libffi C library. Embedding
code is a bug in Debian if there is already an available library and
headers that can be depended on and used instead... so I have taken
the steps to repack the tarball to remove this embedded code-copy in
the Debian package.

However, I am curious to know if this is just a convenience copy, or
if it has any modifications that I should be aware of?

thanks,
micah
