GNU Compiler Collection.

GCC is the GNU Compiler Collection. It provides compiler front-ends for several languages, including C, C++, Objective-C, Fortran, Java, Ada, and Go. It also includes runtime support libraries for these languages.

GCC provides many levels of source code error checking traditionally provided by other tools (such as lint), produces debugging information, and can perform many different optimizations to the resulting object code. The GNU Compiler for Java is now integrated and supported: GCJ can compile Java source or Java bytecodes to either native code or Java class files. Java programs will run faster while letting users run a completely free system without needing a proprietary Java compiler. GCC supports many different architectures and operating systems.
