I THINK we were on the last stable snapshot at the time http://www.portaudio.com/archives/pa_stable_v19_061121.tar.gz 
  .  I don;t think anyone has taken the time to push any patches back  
up.  Some of them for sure are hack types that would not be accepted.   
Others should be merged back, and I would need to see the diff to say  
more which are which.
