/* sndsystem.h -- system-specific definitions */
/* 
  NOTES: you need a different sndswitches.h for each implementation, so
this is a separate file.  Things you need to define here:

1) Either UNIX, WIN32, or MACINTOSH should be defined.

2) Either the following function declaration:
    void snd_fail(char *msg);
or
    #define snd_fail(msg) ...

3) typedef FASTFLOAT to be either a double or a float, whichever
computes faster (PowerPCs are faster at double math than float math)

4) typedef MEMFLOAT to be how you would store a sample in memory
(this should normally be float)

5) min() must be defined (either a macro or a function)

6) max() must be defined (either a macro or a function)
