Features:

You can compile and execute C code everywhere, for example on rescue disks (about 100KB for x86 TCC executable, including C preprocessor, C compiler, assembler and linker).

tcc generates x86 code. No byte code overhead. Compile, assemble and link several times faster than GCC.

Any C dynamic library can be used directly. TCC is heading torward full ISOC99compliance. TCC can of course compile itself.

tcc includes an optional memory and bound checker. Bound checked code can be mixed freely with standard code.

Compile and execute C source directly. No linking or assembly necessary. Full C preprocessor and GNU-like assembler included.

C script supported : just add '#!/usr/local/bin/tcc -run'at the first line of your C source, and execute it directly from the command line.

With libtcc, you can use TCC as a backend for dynamic code generation.

CC386 is a general-purpose 32-bit C compiler. It is not an optimizing compiler but given that the code generation is fairly good. There are two versions; one is for MSDOS/DPMI and one is for Win32. The Win32 version has a full-blown IDE capable of editing, building, and debugging windows programs included with it. However at this time debugging support for MSDOS is rudimentary at best and there is no IDE for DOS.
