It should still be meaningful to use the library without -ieee.
If there are no infinities and no NaNs,
then the functions isinf and isnan should always return false.

It is in the Boost Vault, http://boost-consulting.com/vault/, in the
folder Math-Numerics. The file is called fpclassify.zip.
Try both with and without /float=ieee/ieee=denorm,
and let me know the results.
