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

Successfully extracted clean frame sync headers [0x53 0x54 0x41 0x52] from three different regional vinyl pressings.
Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients.

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

Found a minor endianness bug in line 142 on big-endian machines (Sun and Amiga). Replace ntohl with custom byte swap macro.

Can you provide a pre-compiled DOS binary? Some of us don't have Linux or a C compiler installed on our machines.
