We? Zillions of people still use it -- and it has actively developed forks, like wxDev-C++ (http://wxdsgn.sourceforge.net/) -- but it is an IDE; the compiler it uses is the GCC. The version of Dev-C++ you are using comes with an outdated version of the GCC, so you'll need to upgrade. Just go the MinGW downloads and get the latest version -- download all the files you need, including the Win32 API. Open your Dev-C++ folders and delete the MinGW directory, then unzip/untar/execute/unpack/whatever all the MinGW stuff into a new MinGW directory in your Dev-C++ folders. http://www.mingw.org/http://sourceforge.net/projects/mingw/files/
Good luck!
[edit] Personally, I don't use it nor will I ever -- I can't stand it
