I recall that this issue was already discussed a while ago with some 
people preferring the typedef approach and others (like me) preferring 
to spell out the struct every time to make clear that it's a struct (and 
not a union or some more complex user defined type) we're talking about 
it. In the end it does not matter much as you are probably not writing 
libraries that will be used by a bunch of other people. But if you do, 
I'd avoid typedefs as well as using the preprocessor too much.
