I would also like to point out another perticularity of Apple 
assembler. Contrary to the documentation, multiple statements on the 
same line separated by ';' does not work on Darwin/PPC (e.g. MacOS X 
10.2) because ';' is also the comment delimiter there. This was a point 
of frustration when I ported SheepShaver to Darwin/X11.

In practise, and since you appear to forcibly define __powerpc__ 
(though __ppc__ exists), this means that you will have to arrange 
testandset() asm statements to use \n instead of ';' as the instruction 
separator.

Bye,
Gwenole.
