The Free Software Foundation (FSF) distributes GCC as free software under the GNU General Public License (GNU GPL). GCC is a key component of the GNU toolchain which is used for most projects related to GNU and the Linux kernel. With roughly 15 million lines of code in 2019, GCC is one of the largest free programs in existence. [4]
Cygwin (/ ˈ s ɪ ɡ w ɪ n / SIG-win) [3] is a free and open-source Unix-like environment and command-line interface (CLI) for Microsoft Windows. The project also provides a software repository containing open-source packages. Cygwin allows source code for Unix-like operating systems to be compiled and run on Windows. Cygwin provides native ...
The GNU system required its own C compiler and tools to be free software, so these also had to be developed. By June 1987, the project had accumulated and developed free software for an assembler, an almost finished portable optimizing C compiler , an editor , and various Unix utilities (such as ls, grep, awk, make and ld).

Unix (/ ˈ j uː n ɪ k s / ⓘ, YOO-niks; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 [1] at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. [4]
Being the back-end for a popular compiler suite, namely GCC, the GNU Assembler is very widely used in compiling modern free and open source software. GAS is often used as the assembler on Linux operating systems in conjunction with other GNU software. A modified version of GAS can also be found in the macOS development tools package.
FreeBSD is a free-software Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD [3] —the first fully functional and free Unix clone—and has since continuously been the most commonly used BSD-derived operating system.

The Portable C Compiler (also known as pcc or sometimes pccm - portable C compiler machine) is an early compiler for the C programming language written by Stephen C. Johnson of Bell Labs in the mid-1970s, [1] based in part on ideas proposed by Alan Snyder in 1973, [2] [3] and "distributed as the C compiler by Bell Labs... with the blessing of Dennis Ritchie."
