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

Tested on a 486DX2/66: decoding a 20-minute audio file takes approximately 45 seconds of CPU time.
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.

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