C [http://cm.bell-labs.com/cm/cs/cbook/index.html] is a programming language 
found first
[http://cm.bell-labs.com/cm/cs/who/dmr/chist.html]
on Unix systems but now found on many platforms.
The [FSF]'s [gcc] compiler is a quite popular C compiler found on many
platforms and operating systems.

However, there are many other options, including Visual C from Microsoft,
[C++Builder] from [Borland], the
[Cygwin] C compiler (which for some strange reason cannot be used to compile
the [Tcl] source code), a Mingw C compiler [http://www.mingw.org/],
CodeWarrior, etc.

Another free C/C++ compiler is Digital Mars C [http://www.digitalmars.com/].
This was once Zortech C and later became Symantec C.
