Hi

I'm not sure this is required. So far, CE mode in Hatari will give 
problems with spectrum 512 images and instructions using d8(an,dn) 
addressing mode (eg ULM dark side of the spoon), but apart from that 
many fullscreen are working (transbeauce 2, overscan demos, ...).

As long as "configure" still use old uae cpu by default, I think we can 
leave CE mode by default for WinUAE CPU (especially for people using 
TT/Falcon emulation where CE mode is required for MMU and caches)
