Here is a working development snapshot of GCC (GNU C compiler) for the M68HC05. The newest patched source of GCC is available in the GIT repository. The testsuite is included. The G++ frontend is also build, but not well tested and no support fo libstdc++ is available. Some parts are generated by a php script. php is only needed, if the generation script is changed.
make funclist
can be used to regenerate some parts of libgcc.

Bugs can be sent to me in an Email. Please include the preprocessed input (use -E instead of -c).
