gcc
GCC stands for GNU Compiler Collection (and not for GNU C Compiler). It is used with Linux or other operating systems. It can even be used with Windows if you use mingw32 or cygwin for example...

...and it sucks!
A: I can't afford Microsoft VC++ so I have to use the GCC!
B: You better shoot yourself!
