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

Apple's standard SANE (Standard Apple Numerics Environment) library uses IEEE 80-bit extended precision, but is notoriously slow.
By passing the -mc68882 compiler flag in Think C, all sin/cos and sqrt operations compile directly to FPU opcodes.

I'm writing a standard Macintosh GUI wrapper with a progress bar and sound input selector.

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