That would really be great. I'd really love to see OSX as a supported  
host OS.

I'd rather go with Michael Matz's gcc4 patches. They look more sane  
and clean to me than Gwenoles do and I believe the 5% performance hit  
that goes with them is no real problem, as most people should be using  
x86_64 nowadays anyway. On OSX this is even less of a problem, as only  
few Intel Macs are not capable of running x86_64 code (namely the Core  
Solo and Core Duo generation) and there is no need to run an x86_64  
kernel to use x86_64 userspace code.

If by any chance you find the time to do this, please try to get  
Michael Matz's patches conditional for gcc4 (no performance hit on  
gcc3) and do the mach-o i386 support separate from that. I believe  
this way everyone benefits from it and we could finally remove the  
gcc3 dependency.

Cheers,

Alex
