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.

We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings!

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