+ECL's dynamic FFI (the one that does not rely on a C compiler) is now
+implemented using libffi (See http://sourceware.org/libffi/). Until
+another release in which the library might be bundled together with
+ECL, users will have to make sure that this library is built and
+available for this feature to be linked in (#+dffi). Otherwise only
+the C-based foreign function interface will be available.
