[Qemu-devel] [PATCH] OSX x86_64 host support v2

[Alexander Graf]

Hi,

this is an updated version of the very same patch which fixes a major  
issue that kept interrupts from working and updated to apply to  
current CVS.
Using this patch Leopard is capable of running qemu really fast.

While at it x86_64 Linux gcc4 support should be fixed with this as  
well, as Mac OS X x86_64 requires gcc4.

Please apply,

Alex
