It did the trick. Now SheepShaver rums smoothly and reasonably fast, 
especially when color depth of the host display is set to 16 bit (32 bit 
is somehow slower). This trick doesn't work on the latest CVS version 
(compilation fails after modification).

Now if only did SheepShaver run OS-X... I wish it were, but I am aware 
that it would require adding MMU support, what is a major speed 
bottleneck in PearPC. Nonetheless, it's still fun to play with OS 8.6 on 
my PC. Speedometer indicates that on P4 1.4 SheepShaver is faster than 
real PowerMac 80Mhz. Impressive.

I will play with the crashes with -O2 later (following your advices).
