That compiler is really, I mean really, ancient. And the API changed in
newer gcc (> 3.x.x), so code compiled with later versions isn't binary
compatible. Hmmm. Curtiss-Wright now supports Linux and kernel 2.6.16 on
some of their newer hardware, you might want to check with them or install a
more current distro from Fedora or someone else who supports the PPC.
The python I'm using is Python 2.5.1 (r251:54863) installed as python2.

Any more detail on these? What causes the conflict. I've got to wonder about
the the libc/libm versions also. Does the include file math.h say anything
about the prototypes for these functions? I expect cosl et.al. to be
potential problems on the PPC anyway due to the way long doubles were
inconsistent operand constraints in an `asm',

What is the PPC model number?
