But then I have to specify my size in bytes (chars) rather than bits, right?
Because you're using sizeof. I guess I could just do sizeof(typename
TL::first_type)*8 >=MINSIZE), right? (I will assume 8 bits to the byte).

I like that you don't actually have to know the sizes of the integer types
to do the specializations for them.

    ... and just specify that the "precision" ... A bit-field whose size is CHAR_BIT, can certainly be represented by a char; bit fields of a larger size clearly cannot be represented as a single char. ... Also, the standard requires that if a bit field with a width of 3 is followed by a bit field with a width of 4, then if there's enough room in the allocation unit, they must be allocated in adjacent bits within that allocation unit; that's pretty hard to do if you implement them as chars. ...
