I see what you are saying.
In my case I keep other peoples code very separate from mine, for VCS reasons. I could still move directories around to make this usable (it wouldnt by any chance support environment variables would it? I have not checked), but like I said, was just hoping a change to the compiler so that I could make a single change to a setting in the IDE was easy enough (and more in line with ANSI C
) as compared to changing/managing include lines in many programs. Maybe at some later point, it is not creating any problems at the moment.
