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.
Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.

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

Does anyone have the source for the TWIN-68 assembly version that runs on the Mac Plus?

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy.
