What does "pipe a wav file" mean?  I was testing this by doing:

cp h.wav /dev/dsp

But there seemed to be something inexplicably wrong with the 32-bit
snapshot.  The cygwin dll was incorrectly built.  I don't know how
I could have done that but the new snapshot seems to work better.
The old snapshot didn't work for me at all even though my locally
built non-snapshot builds worked fine.
