Third, I like your rcc.h, using the union for structs. In my opinion
this makes things a lot cleaner. This is also has been a bit of a
contention for the project between several of us. :-) Two things on
this.

1) rename val to raw, it keeps it consistent with other locations
where this has been in use.

I think he got that from scs.h, which uses 'val' and 'bit'. Maybe we
should rename 'val' to 'raw' there as well.
