GNU Compiler Collection is a Scripts software developed by GCC Team. After our trial and test, the software is proved to be official, secure and free. Here is the official description for GNU Compiler Collection:

Edit by Marydown: The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, and Ada, as well as libraries for these languages (libstdc++, libgcj,...). GCC was originally written as the compiler for the GNU operating system. The GNU system was developed to be 100% free software, free in the sense that it respects the user's Freedom.

We strive to provide regular, high quality releases, which we want to work well on a variety of native and cross targets (including GNU/Linux), and encourage everyone to contribute changes and help testing GCC. Our sources are readily and freely available via SVN
