I agree. c_xxx might look ugly, but it is even more helpful for making the code readable than other coding rules.

I actually agree fairly strongly that constants and global/static variables should have consistent, identifiable prefixes.
For globals, having a prefix code easier to understand with a quick scan. If the global has no prefix, you have to search for it and discover that it's not a local variable, member variable or parameter before understanding where it comes from. This is a particular problem in Xcode, which does not use a different syntax highlight color for globals (unlike the venerable CodeWarrior). I also think that globals are a particular concern because they impact thread safety, and misunderstanding their scope of influence can have bad ramifications.
