--- Comment #18 from Dennis Clarke <dclarke at blastwave dot org> ---
We are saying the same thing here. 

Those same emulation routines exist elsewhere and are called _Qp_div,
_Qp_mul and _Qp_add on Solaris SPARC systems whereas those are 
implemented into other places with more or less the same names. 

Let's not go in circles here.  I see the issue and the old 970 is a
historical artifact.
