John,

Could you test the latest version (ver. 13) of my fpclassify library?
It is available in the vault in the directory Math-Numerics.

The library is based on a helper class fp_traits<T> that contains
information about the binary representation of T.
Here T = float, double or long double.
The generic version of fp_traits<T> is initialized at run time,
and is hence safe but also slow.
Then there are fast specializations of fp_traits<T> for different 
floating point types T, operating systems and processors.

The library does not use the limits and boost/endian.hpp headers.

The library has been tested on the following platforms:

   Win / MSVC 7.1 / x86
   Mac / GCC 3.3, GCC 4.0 / ppc
   Linux / GCC 3.3 / x86, x64, ia64, ppc, hppa, mips, m68k

Let's see if you can break it!
