That's the right fix.  If you didn't, go ahead and put it in.  Thanks!

Nope; we don't want to waste the space for simple types.  We should be
being careful.

In lots of the code, it checks TYPE_LANG_SPECIFIC outside of the
macros.  Often that's silly; the checks should be in the macros
themselves for the most part.  However, some of the macros are used as
lvalues so they can't have conditions in them, and in some places we
know things are safe.
