Ok, thanks. I'll try everything else first, then try this if I get
desperate. The main thing I hit a wall with was when I switched to
floating-point, which increased my .lx filesize by about 2k, so if I go
back to fixed-point, turn sound off in config.h, and watch my stack sizes
in my execi I'll probably be ok. If I do happen to try -Os, I'll certainly
write back and say how it went.
