In a quick look at it, I don't see where the _Classify function properly handles 
the Intel 80-bit long double format, which has the fixed msb set in the 
significand--which needs to be ignored in the INF/NAN check.  If it does, could 
you point it out to me?

By the way, I have almost all of the long double functions done, but am still 
probably a couple of weeks away from getting the last details done to be able to 
submit the first piece.  The strtold that I mentioned a couple of weeks ago is 
the first I am working towards, but it requires some infrastructure that I have 
to resolve, and time to work on it has been hard to come by.  Once I get that, 
I'm planning on putting in strtold.  After that there's lots more.  The stuff I 
have has been tested with Intel 80-bit (the biggest nuisance because of that p0 
bit), as well as 128-bit on SPARC.  Of course, if others get there first, that's 
OK, since I have been very pokey on it.
