ShowConfig shows CPU 68040/68030mmu

Why this ?
In Config a have checked CPU=68040 and JIT=ON.
Same is, if i checked CPU=68040 JIT=OFF 68040MMU=ON.

Is this a Bug in WinUAE or in WB3.1 (AmigaForever Diskimages)
I load only WB3.1/Extras3.1 from "Disk", no other Patches or something else.

Oh i forgot, its WinUAE 2.3.3 final.

Safe 68030 MMU detection is practically impossible. Some 68EC030 versions can hang when any MMU instruction is executed so most programs assume full 68030. (Documentation says MMU instructions are "undefined" on EC030..)

There is no 68040 CPU version that has built-in FPU without MMU. (EC040 = no MMU and no FPU, LC040 = MMU only) Safest solution was to leave MMU instructions emulated (which do nothing in non-MMU emulation mode).
