Um, not ideal since the data makes much more sense as bytes -- it's bitmapped
definitions for the character set, and it helps to be able to check the
accuracy of the definitions visually (or at least it did when I was debugging
that section). I like to keep data in the most easily-interpreted form
possible, such as the binary-constant macros that I posted and use for things
like single-plane gadgets.

PS I ended up using a union, 8 bytes or 2 longs.
