I got it. I also got it from a few others. I also decreased the size of SDCC's
output from 0xb3 to 0x9d (or 179 to 157) instructions. Byte Craft's compiler
produces a 151 instruction version. That's 6 instructions that I can't account
for. Perhaps if I rewrote the startup code...
Thanks Matt (and others)
