SCM

An open source multi-platform implementation of Scheme written in C, SCM is an interpreter. It includes a Scheme-to-C translator called Hobbit that generates C files which can be linked with the SCM executable. The program is primarily developed on Linux and Microsoft Windows these days but it has support in the source for the Amiga, DOS, the Atari ST, MacOS, OS/2, NOS/VE, Unicos and VMS, Unix and uses mostly common I/O libraries so should be a fairly easy port to other operating systems that have some POSIX compatibility.
