Apologies for the long post.

I decided it would be useful to see how the C version of the ieeefp-tests works. I've appended the double-float output file generated via GCC on a sparc/solaris8 box.

There are some surprises there. CMUCL/sparc has failures on cosh and sin. The C version shows no such errors, but does shows errors on atan2, which doesn't happen on CMUCL/sparc.

More study needed, I think.
