No.

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
explanation.

:) Sorry, it wasn't my intention to cause much discussion, trouble or
work for maintainers with that patch. I don't feel strongly about, I
just stumbled across it when browsing the source and found it odd to see
a macro defined just below the #include of a header which defines the
same macro.

Please just ignore the patch then :)

Thanks
