Don't waste your time with the GCC 4.3.2 sources. They only have a 68k code generator for embedded systems and would need you to adapt the Geek Gadgets binutils sources to run it at all. I think the last GCC for 68k processors on the Amiga was version 3.4.0. You can get it on
the Back to the Roots website. Look in the Geek Gadgets archive.
