Besides just the CDT what do you find essential for c development using eclipse?
Is subclipse mature/reliable?

                It works well enough, I don't remember having to correct something with command line commands.But it may be too slow if you don't use it with the javaHL library.

            If you're doing development on Linux, then Linux Tools is very useful.

              I normally use cmake to build C++ projects. Recently I have been using the Eclipse CDT4 Generator and it works quite nicely, see this link or this one.
I have tried on Linux I don't about Windows. I know this project is trying to make easier develop with C++ on windows using Eclipse but it still have pending things.
