Software that is developed and distributed under so called GNU Copyleft is called GNU Software. That more or less means that it is available for free under condition that you must not resell it or sell it as a part of something else that you developed. Among many available C and C++ compilers there is one for Windows, called MinGW. Using the pure "compiler" would require accessing it from the so called console mode (DOS Window). because that approach is not very convenient someone wrote a simple text editor that interfaces nicely to MinGW and called it Quincy. You can download MinGW separately. However, Quincy comes with minimal distribution of MinGW that is suffcient to compile console and GUI programs for Windows in ANSI C and C++ with STL. The original Web sites are located at: MinGW Quincy .
