OK.  Sadly we already have a dependency though (at the top of
c_common_init to set CPP's idea of whether wchar_type is signed or not, as
I commented there).  This made me want to find a better way of defining
the target types rather than textually like now (and somehow making
the *_TYPE_SIZE versions redundant, which they are, at the same time).
However, I couldn't immediately think of anything as a replacement that
would allow us to easily determine its size from the target macros giving
the sizes of the basic types.

You're good at that kind of thing, any ideas?

Sure.
