The file LIBGCC.ZIP contains some fundamental functions needed by gcc in order to perform floating point operations etc. (In the m68000 case you even can't perform integer multiplication/division without it!) PKUNZIP it and place it in m68k\lib\ replacing libgcc.a there. The libgcc.a included in m68k.zip just contains empty functions. Maybe you need to make your own libgcc.a to optimize your particular CPU or of some other reason, this libgcc.a is just one possible implementation.
