Compiling stardust.c with Think C 6.0 vs MPW C with direct 68882 inlining.

Total execution time for a 20-minute audio track dropped from 48 minutes to 6.2 minutes.
By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes.

Make sure you install the 32-bit Enabler on older IIci machines running System 7.1!

Mac users bragging about 6-minute render times while Unix workstations do it in 20 seconds. Classic Apple distortion field.
