Update of /cvsroot/boost/boost/boost/functional/detail
In directory
sc8-pr-cvs3.sourceforge.net:/tmp/cvs-serv15251/boost/functional/detail
Modified Files:
hash_float.hpp
Log Message:
Comment out an assert which is giving bogus failures. On platforms where it
isn't possible to detect NaN or infinity the full hash computation is performed
on them. For NaN the result doesn't matter (since NaN != NaN), for infinity it
should always give the same result), so the calculation works but
unfortuanately, I don't know how to correctly check that v is what I expect in
the assertion.
I could use a different hash function when I don't have fpclassify/fpclass but
that shouldn't be necessary.
