The GNU Compiler Collection includes compiler front ends for C, C++,
Objective-C, Fortran, OpenMP for C/C++/Fortran, and Ada, as well as
libraries for these languages (libstdc++, libgomp,...).
GCC development is a part of the GNU Project, aiming to improve the
compiler used in the GNU system including the GNU/Linux variant.
