Many thanks to both Stjepan and Jeremy for running these, I have a couple of 
observations/questions:

The error rates all look to what I would expect from an 80-bit (64-bit 
mantissa) real, but I thought the Mac used a 128-bit "double double" type?

So... which OS version are you using, is this one of the new "MacIntels" or 
one of the older Motorola-based machines?

Also can you build and run libs/config/test/math_info.cpp and let me have 
the program output: this will let me see a lot of useful limits-related 
info.  If we can nail the low hanging fruit first, I can look into anything 
else left later.

Many thanks for doing this, John.
