What is Helium? Helium is a minimalistic real-time kernel for the HC(S)08 core by Freescale and Atmel AVR.

Update. Future releases of Helium will compile with gcc. Codesourcery provides a pre-compiled command line toolchain featuring gcc, g++, etc. as well as linker scripts and startup code for the 68k/Coldfire architecture. Instructions for building a cross-compiler on Mac OS X with gcc are here.
