It was a reply to the subject.
You don't need 68040.library with WinUAE. WinUAE 040 emulation doesn't emulate MMU at all, and afaik proper cachemode setup is done by UAE itself (gfxcard framebuffer, custom, cia are noncacheable and so on...).
PS. There is a experimental MMU patch for UAE, but it slows emulation down quite abit, and is less stable (I've heard). With this version you could use 68040.library, I suppose. No idea which one.
