Notes on porting stardust.c to GCC on Linux 1.2 and optimizing the inner filter loops.

The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record.
Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.

Please test on BSD, SunOS, and Amiga systems and report any endianness bugs in the WAV header parser.

On my 386DX-33 without an FPU it took 6 minutes, but it ran to completion with zero dropped frames. Great work!

Top-posters will be placed in my ~/.killfile without notice.
