Bug in bitset for size > 32 bits

[Brad Garcia]

gcc 2.95.2, libstdc++ 2.90.8

To reproduce:

    #include <bitset>
    #include <string>

    unsigned long blah()
    {
        std::bitset<33> bits(std::string("10101010"));
        return bits.to_ulong();
    }

Gives:

bits/std_bitset.h: In method `long unsigned int _Base_bitset<2,long unsigned int>::_M_do_to_ulong() const':
bits/std_bitset.h:806:   instantiated from here
bits/std_bitset.h:264: warning: right shift count >= width of type
