My gcc-4.8.3 doesn't. (By default I've enabled all the warnings I know of, in
addition to -Wall; perhaps I'm just missing something).

Some people like typedefs, others don't. I've tried to find out which is
better, and I ended up having no real opinion on it.
(I initially didn't add a typedef, because I know it's not always favored.
Personally, I use typedefs a lot, as I see it as a part of the C-language).
As for myself, I'm hoping that I can set up GDC (dlang.org), so I can get a
Cortex-M toolchain that supports OOP without the C++ kludge. ;)
