It worked for me. I got the lastest from the beta3/c_tools directory,
modified the user.cfg and off they went.

The bit script uses links and it seemed to build. I have not built
anything with the m68k compiler yet.

This is what I am building.

I used egcs-1.1b (not that a to b is a real change), binutils-2.9.1,
newlib-1.8.0 and Joel's patch.

I used egcs-1.1b and binutils-2.9.1 on Linux to build the tools with.
