VC 6.5 is on the list of platforms officially supported by Boost.
Maybe it should be removed.
It is hard for me to imagine that anyone still uses it.

I have uploaded a new version of fpclassify, ver 16, that has been 
tested on

Win / VC 6.5, 7.1 / x86
Mac / GCC 3.3, GCC 4.0 / PowerPC

Next a friend of mine will test on Linux / GCC 3.3 and half a dozen 
different processors.

John, once that is done, you could try again.
