What would you change in C?

It's the time for the next revision of the C standard and for some reason they want your advice. What do you add, remove, rename, etc ?

I would remove most of the shit in C99 that nobody has implemented anyway. Other than that, C is perfect and changing it requires renaming the result because it isn't C. I will admit, however, that adding namespaces and function overloading would be nice.
