Ah, another Amiga-User :)
Maybe it's because the 68k uses 80-bit precision internally
while the PPC uses 64-bit precision.
I don't think that libmoto.a makes any problems, but you could
try fdlibm.a to check...
BTW: Which Kernel do you use (PowerUp or WarpOS)?

Software suppliers are trying to make their software packages more
'user-friendly'.... Their best approach, so far, has been to take all
the old brochures, and stamp the words, 'user-friendly' on the cover.
