What Refactorings Would you Like for C

Hi I'm currently a student working on an honours-level project to
create a visual tool which will be able to represent C project files
and code as well as allow the user to perform high and certain low-
level refactorings.

At the moment I'm compiling a list of refactorings which are
applicable to C that people who program alot with structured
programming languages find useful.

So far I've got (some I got from someone else's post on another google
group):

- Rename variable/function
- Move variable/function
- Reduce scope of variable
- Publish function (make it public, put a declaration in the .h file)
- Perish function (make it static, remove it from the .h file)
- Add/Remove parameter from function
- Reorder function arguments
- Remove unnecessary includes

Cheers
