+ `(*****)` Enums are now handled like ints (unsigned or signed, int or
+ long, like GCC; note that the first choice is unsigned). In previous

their value symbolically, use code like ``if x.field == lib.FOO``.
If you really want to get their value as a string, use
``ffi.string(ffi.cast("the_enum_type", x.field))``.
