And what would I have gained apart from typing 3 characters less?
Suddenly I have to lookup the real type in another header instead of being
told that it is an enum.  I see absolutely no gain from this procedure.
I'm not alone with my opinion; cf. the Linux style guide wrt typedeffing
struct names.

Also, the _t namespace is reserved by POSIX, this particular name would
invade it even more.
