Typedef has always worked in C.

Not for LLVM, but it has in other projects like I mentioned.

None of those projects use cmake, so it doesn't look easy to run clang-tidy on them. Do you have a script that will run clang-tidy on these repos?
Actually, PVS-Studio has a more general check for `sizeof(expr)`:
It shows an example of FCEUX doing `sizeof(buf - 1)`, Asterisk doing `sizeof(data * 2)` and ReactOS doing `sizeof(UnknownError  - 20)`. I think it might be a good idea to expand this from just a function call to any integer expression.
