[boost] [hash] Return type of fpclassify on gcc 4.0.1 on Darwin/OS X

The hash floating point tests are failing on Darwin. Looking at the 
error (http://tinyurl.com/qoehb) it appears that when called with a long 
double, fpclassify is returning a value that isn't FP_ZERO, FP_INFINITE, 
FP_NAN, FP_NORMAL or FP_SUBNORMAL. But according to:

http://developer.apple.com/documentation/Darwin/Reference/ManPages/man3/fpclassify.3.html

those are the only values that it can return.

I've been reading up about OS X's long double implementation but can't 
find any mention of fpclassify. So maybe I just shouldn't use it on this 
platform.

Please can someone with access to the platform look into this?
