Refactoring tool in C code

I'm looking for a tool that can use refactoring types (!) In C code.

I have a complex and relatively large code base where we decided to move from built-in integral types to explicit width types. Like changing all instances of "unsigned int" to "uint32_t" and the like.

I know there are many refactoring tools out there for naming conventions, but none that I know can contain the entirety . For example, Visual Assist can reorganize "long" as a single token, but cannot reorganize "unsigned long".
