Fixing C

How to fix C?
What don't you like in C?

I do not like the many useless types while we could just define our own n-bit integer
also a a better typesystem for compile time checking would be nice
I also would like pure functions that I would be able to use outside of functions just like I do in macros

I now realize this isn't related to this thread. But I'm going to post it anyways. Because I want C to do this too. Although I don't quite understand what I want it to do.
