Have you tested this on a system without PA? I think you should also exclude
PA-specific sources if use_pulse_audio==0.

[slock, 2011/08/08 22:08:49]

Done.  Definitely, for the use-case of the person trying to compile on Linux
without PA.  There won't be any such system readily available around the office
though as Goobuntu has PA built-in.
Also of note, I considered excluding PA for FreeBSD and Solaris but decided not
to for now (and probably won't in general).  PA exists for/has been tested for
those systems and there is easily available evidence of people actually using it
on those systems (though with mixed results).
