This starts to have the feeling of a Bug Week. ;) Cheers to everyone  
else testing or fixing.

To complete my test report from OSX/ppc as requested:

It turns out that I can compile QEMU with gcc-3.3 on Leopard/ppc with  
the always_inline fix applied: QEMU's recursive redefinition of inline/ 
always_inline seems to break Leopard's headers rather than gcc3 itself.
