The point is that an M68060 user should be aware of the FPU
implementation in the M68060 cpu.  Therefore, as the User's Manual
recommends, the user should install the M68060SP for proper
compatibility.  Using a M68881/2 is not an option anyway, so follow the
manufacturer's advice, otherwise you might encounter performance
penalties or, much worse, incompatibilities.  Code that is executed as
fast as possible but returns wrong results is useless.
