[B2-devel] SheepShaver for x86

Fixed in current CVS.

However, there is another bug lurking around but you can still boot 
without extensions and run applications (tested MacOS 8.1). On a P4 @ 
1.8 GHz, Speedometer 4.x reports speeds around 1.7x of a real Quadra 
605 (approx. 50% slower than B2 without JIT). Now next step is 
abviously to write the JIT. ;-)

You will also need the following patch until a real fix appears.
