[Qemu-devel] [PATCH] Fix build if OSS_GETVERSION is not defined

[Juergen Lock]

In this case it was missing on FreeBSD <= 6.x  (Which also doesn't have
SNDCTL_DSP_POLICY yet so the version doesn't get used anyway.)

 ...these last two lines (#else and 0) probably should go, I dont think
the compiler likes whitespace between digits. :)

 And also I forgot to say this is stable-0.12 material too.

 And thanx for committing!

 Oh sorry I should have guessed not all committers do merges to stable
branches...  Anthony? :)

In this case you should probably resubmit one accumulated top-level  
patch marked [PATCH][For stable-0.12] or similar (instead of having  
two commits cherry-picked).

Ok I can do that, but first I have another patch to the same code,
turns out the ioctl doesn't actually work yet on FreeBSD even if it
is defined...
