I have some strong feelings about that: namely, a typedef should be used
for *any* type that is supposed to be opaque.

If my program does not need to know whether something is a struct or a 
scalar or whatever, it *must not* know it either.  This tends to make
interface maintenance trivial (i.e. you have to recompile the interface
consumers, but you don't need to patch their sources as well).

MHO, naturally :)
