Sure, replacing the TRUE with FALSE will make the whole thing compile, with 
the ALSA code disabled. Otherwise the code wouldn't be portable to non-
Linux...

But using Phonon like that on Linux... better to disable Phonon altogether. 
Your Phonon-Xine will use an ALSA device without dmix, so no concurrent 
access. The requirement for ALSA is there because I cannot support anything 
else on Linux.
