Thanks. This is exactly the detail I needed. Let me comment on each
item.

That last LIBS grows as configure runs, so that is why reordering fixes
things for SCO.
I don't see any immediate downside to moving it so I will apply the
change to 7.3. Any platforms problems with the reordering will show up
during 7.3 beta testing. I would need someone else to agree before
making this change in 7.2.X.

Yes, the patch replaces pow(8,*) with a lookup table of 4 8^X values.
So SCO provides a library you can't link to? Or you can't mix *.so
libraries and static *.a libraries? I am inclined ot add this patch to
the doc/FAQ_SCO file. We really try to avoid major code uglyness to
work around operating system things that should work on their own.

Not sure how to deal with this one. Can you add something to FAQ_SCO or
should I add this patch. Clearly this is very OS specific and probably
only true for certain versions of SCO.
