Exactly. This is relevant to interoperability with C, which on
little-endian machines usually packs bit-fields into bytes little end
first. So I don't think there's a neat way to describe a structure like
the following in Erlang.

        struct {
                int a:4;
                int b:8;
                int c:12;
        } s;

Tony.
