[Tuxnes-devel] patch: don't create /dev/dsp

[Allen N. <psy...@ge...>]

Here's a little patch to make tuxnes stop trying to create /dev/dsp as a regular
file with undefined mode. Incidentally, it also allows tuxnes -smute to start
while another process is hogging /dev/dsp.

InitAudio will still try to create the audiofile later, but it gives a mode, and
I suppose it could be useful for recording sound output.
