For Stallman the idea was pretty clear. All he required is to make an operating system which is UNIX compatible so that it must be easily portable. the word GNU was chosen following a hacker tradition, as a recursive acronym for  "GNU' s NOT UNIX".
  The GNU project started with an objective to create free software society. Here the term "free" is often misunderstood for the price of the software. It has nothing to do with the price, its about the freedom. Its defined as:
  •  you have the freedom to run the program for any purpose.
  • you have the freedom to modify your programs as it suits your need. (for this you need to have access to the source code).
  • you have the freedom to redistribute the copies either for a fee or gratis.
  • you have the freedom to redistribute modified versions of program, so that the community will benefit from your improvements.
So Stallman quitting his job from MIT in 1984 started designing a compiler for the operating system which is popularly known as GCC. GCC compiler has been universally accepted and widely used till date. Compiler is one of the core application in an operating system.
