4.1 GNU Compiler Collection

The GNU Compiler Collection (GCC) consists of utilities that you can use to compile programs, written in languages that include C, C++, Objective-C, Objective-C++, and Fortran. The GCC provides compilers such as gcc and g++, run-time libraries such as libgcc, libstdc++, and libgfortran, together with other useful tools.

The version of GCC in Oracle Linux 6 is based on the 4.4.x release series, about which you can find more information at http://gcc.gnu.org/gcc-4.4/.

The C compiler in GCC 4.4.x is largely compatible with the C99 ABI standard. For information about deviations from the C99 standard, see http://gcc.gnu.org/gcc-4.4/c99status.html.

For more information about compliance with language standards in GCC, see http://gcc.gnu.org/onlinedocs/gcc/Standards.html#Standards.
