Wow, I guess I was overzealous with the optimizations. Upon further
testing, I discovered that the Numeric stuff did not work properly on
Intel machines, but did work properly on m68k. I dropped the
optimization to -O2 (leaving out the -fschedule-insns2), and it seems
to behave properly on both architectures now.
So,
make "OPT=-O2 -ObjC -arch m68k -arch i486"
looks like a better choice.
Sorry for the misguidance,
