   The weird (and unusable) results are caused by the IBM representation of
   quadruple as two doubles.    In other words, DLAMCH has not been written
   in a sufficiently portable way.

   DOES ANYBODY KNOW THE CORRECT VALUES?

I'm sure that that information is IBM proprietary :-)

(The source of dlamch refers to a few papers with algorithms.
You might try to find out what assumptions about the architecture
they use that are not applicable to the RS/6000)
