Errr... the major part of the 68040/68060.library is not related to "cpu fixes" or "patches", but they provide the full set of transcendental functions on the FPUs of both chips which are supported by the 68881/882 but not the 68040 and 68060. This is hardly a fix. In the same sense, a Vampire would also benefit from such a system for every FPU instruction that requires execution in full (extended) precision the Vampire does not support - it has also a limited FPU that computed with a restricted precision, but does not implement a trap mechanism to allow emulation of an extended precision computation. Instead, it provides just a restricted precision result. I would hardly call that "better".

But it *should* need something like it. I mean, instead of computing with a precision below double instead of extended, even if extended was requested.
