The CPU libraries are there to deal with any incompatibilities that might arise from CPU-specific features, relative to the 68000. They offer a standard method of dealing with such things as CPU traps, which can occur when a CPU meets an instruction it can't deal with. In these sorts of cases, the library can offer a work-around instead of the system simply crashing. This method is used in the 68040.library and 68060.library files for replacing the missing FPU instructions that were present in the 68882, for example.
