    I had some access violation faults when running the OV. This patch 
is a little shortsighted one since I didn't search for a clear policy of 
the allocations of _Tracks[] elements, nor wanted to enforce one. Thus I 
only NULL-proofed the tracks availability checks. It does correct the 
hangups here.

    Applies the VC7 naming convention to the DLLs names (this was left 
as a copy/paste of the VC6 code and #ifdef'ed 0)

  http://zerodeux.net/misc/nel/sound_driver_dsound.patch
    Fixes a simple associativity ambiguity.
