Ah, I didn't know it was non-qemu code (but now that I look at it again,
I probably should have realized that sooner ;). Thanks for the

:) Sorry, it wasn't my intention to cause much discussion, trouble or

a macro defined just below the #include of a header which defines the
same macro.

Please just ignore the patch then :)
