Small Device C Compiler SDCC http://sdcc.sourceforge.net/
SDCC is a freeware, retargettable, optimizing ANSI - C compiler, that runs on Linux and MS Windows 95/98/NT.
SDCC will compile natively on Linux using gcc.  Windows users will need to download the full development
version of CYGWIN32, or download a pre-built WIN32 binary.

The Retargetable Concurrent Small C (RCSC) compiler
RCSC is downloadable from Dr. Dobb's at the ftp directory ftp://ftp.ddj.com/1997/1997.08/
