Hi Vladimir,

It appears to be a bug with the Intel compiler.

Along the lines you suggested, here is an example. Note that it needs the
using namespace std and the 3.14f (explicitly f and not default or d) to
appear.

The Intel team is aware of the problem.

Thanks
b.

/tmp> cat test.cc
#include <iostream>
#include <cmath>

using namespace std;
int main()
{
    std::cout << isfinite(3.14f) << std::endl;
    return 0;
}

/tmp> icpc test.cc
/usr/include/c++/4.3.3/cmath(522): error: identifier "__builtin_isfinite" is
undefined
        return __builtin_isfinite(__type(__f));
               ^
          detected during instantiation of
"__gnu_cxx::__enable_if<std::__is_arithmetic<_Tp>::__value, int>::__type
std::isfinite(_Tp) [with _Tp=float]" at line 7 of "test.cc"

compilation aborted for test.cc (code 2)
