[Bug libstdc++/25913] New: Client's isnormal function is broken by cmath

["hhinnant at apple dot com" <gcc-bugzilla at gcc dot gnu dot org>]

I believe the program below should compile:

#include <cmath>
#include <string>

struct employee
    : private std::string
{
};

struct manager
    : public employee
{
};

bool isnormal(const employee& e)
{
    return false;
}

int main()
{
    manager m;
    bool b = isnormal(m);
}

cmath: error: invalid cast from type 'manager' to type 'double'
