(See also [Tcl and other languages], and [Critcl])

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.

http://www.eskimo.com/~scs/C-faq/top.html

The ANSI comittee as well as the ISO comittee have approved a standard
reference for C.

See http://www.lysator.liu.se/c/ for pointers to various papers.

Support for C is traditionally provided by a compiler. 

The [FSF]'s [gcc] compiler is a quite popular C compiler found on many
platforms and operating systems.

Also, most Unix systems have vendor supported compilers.  They are often unbundled products these days. Sun is one of the vendors who have this type of product.

There is also [tcc], the "Tiny C Compiler".

[[In the following list, be certain to indicate whether or not you have built Tcl and Tk with the compiler in question.]]
On [Microsoft Windows] there are many options,
including
   * Visual C++ from [Microsoft] (commercial),
   * [C++Builder] from [Borland] (commercial; an older command-line version is still available as a free download),
   * the [Cygwin] C compiler (free; a version of [gcc]; for some strange reason it cannot be used to compile the [Tcl] source code out-of-the-box - but Cygwin comes with its own version of Tcl at least),
   * the [Mingw] C compiler [http://www.mingw.org/] (free; another version of [gcc] for Windows with goals slightly different from [Cygwin]),
   * CodeWarrior [http://www.metrowerks.com/MW/Develop/Desktop/Windows/default.htm] (commercial),
   * Digital Mars C [http://www.digitalmars.com/] (free), which was once Zortech C and later became Symantec C,
   * LCC-Win32 [http://www.cs.virginia.edu/%7Elcc-win32/] (free) [[Can that compile Tcl itself?]],
   * Intel C++ compiler [http://www.intel.com/software/products/compilers/] (commercial)
   * OpenWatcom C++ compiler [http://www.openwatcom.org/] (free?) [[No idea if it can compile Tcl.]]
etc.

The number of C compilers available on [MacOS] is more limited.  There is

   * CodeWarrior by Metrowerks [http://www.metrowerks.com] (commercial) for [MacOS Classic] and [MacOS X],
   * Apple's MPW for [MacOS Classic] (free download),
   * [gcc] for [MacOS X] (free; download from Apple); either used stand-alone or with Apple's ProjectBuilder IDE (included in the download).

Support for C can also take the form of an interpreter. 

For instance, a recent advertisement for Ch, a product at
http://www.softintegration.com/ , is interesting.  It is a C/[C++]
interpreter that runs cross-platform on a large number of operating
systems and hardware.  It provides not only standard language features,
but also support for 2 and 3 dimensional plotting, shell programming,
and numerical programming.  It supports 1990 ISO C standard as well as
C99 features.  In Jan, 2003, the product page for Ch Standard says that
the product is free for use on Unix, Linux, and Mac OS X.

Support for C can also take the form of a run-time compiler.

[tcc] provides a libtcc library, which allows a running program to compile
and link C code without touching disk.  In milliseconds for a small chunk
of code.  (x86 only as of Jun 2003)
