A significant number of internal C users have been complaining about the lack of support for fixed enums. We already support this in Objective-C mode, as well as in C mode with -fms-extensions. Supporting this in C makes us more consistent, and provides a useful feature to C users!

If there is some doubt as to whether we want this, I can start a thread on cfe-dev for the wider audience.
