--- Comment #1 from Will Wray <wjwray at gmail dot com> ---
Hmm, the accepted simplified version ^^^ with typename parameter removed
is then rejected if 'unsigned' is replaced with 'uint32_t' from <cstdint>

    #include <cstdint>
    template <int width, int offset>
    struct uint_offset_bitfield { uint32_t : offset, field : width; };
    |                                      ^
    | error: found ':' in nested-name-specifier, expected '::'
    |                                      ::
    | error: invalid use of '::'

(and "error: invalid use of '::'" is just wrong - no use of '::' at all)
