Currently ECL does not support this in the original sources because FFI has
evolved into a very complicated set of sources that cannot be built with
Microsoft's compilers: it demands mingw and other tools.
This may have changed recently, I do not follow libffi so closely, but, as
I said, the problem is not that ECL cannot be linked against libffi using
Visual Studio, it is just that I do not know how to do this integration
smoothly without further dependencies.
A more reasonable alternative that works on all ports (and is much faster)
would be to compile your code before loading it: it will just work even
without dffi. The FFI is only needed to create the wrappers, but once they
have been compiled they work regardless of the underlying implementation.
