when i try to implement bimap, i have the following compiling error.

[kuo7288@…]

../boost/boost/functional/hash/detail/hash_float.hpp:65: error: call of overloaded ‘fpclassify(float&)’ is ambiguous

gcc/x86_64-redhat-linux/4.4.6/../../../../include/c++/4.4.6/cmath:497: note: candidates are: typename gnu_cxx::enable_if<std::__is_arithmetic::__value, int>::type std::fpclassify(_Tp) [with _Tp = float]

I have no clue why this is happening, i thought it was fixed ​https://svn.boost.org/trac/boost/ticket/2033

Replying to kuo7288@…:

Today I compiled with template <class T>

inline std::size_t float_hash_value(T v) {

using namespace std;

compilation conflict,

was added before fpclassify to help out with compilation switch (::fpclassify(v)) {

Can someone fix this problem please on the next release, std::fpclassify(v) also works
