And is slightly screwed up, as i noticed while re-checking and
re-merging into our sources.

I screwed up sdbbp here, the entries I added I32 to were incorrect
(wrong encoding). Obviously should have been testing it. 8-S

This is now unnecessary/irrelevant, since the previous sdbbp formats
aren't appropriate for I32.
*sigh* Anyway, I'll have to reissue this one, and the changes will
cause conflicts for later patches -- more later.
