[Boost-users] [1.41.0] Intel 11.1 Linux vs. cmath header

I am trying to build the Boost 1.41.0 libraries with an evaluation copy 
of Intel C++ 11.1 for 64-bit Linux.  My system is Fedora 12 with G++ 
4.4.3 installed as the default compiler.  This fatal error is preventing 
most of the libraries from building:

/usr/include/c++/4.4.3/cmath(500): error: identifier "__builtin_fpclassify" is undefined
        return __builtin_fpclassify(FP_NAN, FP_INFINITE, FP_NORMAL,
               ^
          detected during:
            instantiation of "__gnu_cxx::__enable_if<std::__is_arithmetic<_Tp>::__value, int>::__type std::fpclassify(_Tp) [with _Tp=float]" at line 65 of "./boost/functional/hash/detail/hash_float.hpp"
            instantiation of "size_t={unsigned long} boost::hash_detail::float_hash_value(T) [with T=float]" at line 282 of "./boost/functional/hash/hash.hpp"

I am building the libraries with this command:

bjam toolset=intel-linux threading=multi variant=release link=static,shared --stagedir=stageIF12 stage

Release notes seem to indicate that someone has successfully built Boost 
libraries with Intel 11.1 and G++ 4.4.1 (whose cmath header looks the 
same as for 4.4.3).  I have not used the Intel compiler for several 
years, so I may be missing something that is familiar to other users.

Help?
