Compiling LibreCAD with Visual Studio 2010

These days ,I  compiled LibreCAD with Visual Studio 2010,
I encountered some problems:Visual Studio 2010 does not support C++99，such as

class RS_FileIO {
private:
    //singleton
    RS_FileIO();
    RS_FileIO(RS_FileIO&) = delete;
    RS_FileIO& operator = (RS_FileIO&) = delete;
.....
}

these process ,I solved the following problems:
msvc complains that more than one overloaded functions matches:
std::ofstream << (double) x;
msvc complains that it could match both of the following:
std::ofstream << double
std::ofstream << long double

just noted these codes:
/*
inline ofstream& operator<< (ofstream& ofstr, const DWORD& output)
{
        ofstr.write((char*)&output, sizeof(DWORD));
    return ofstr;
}

inline ifstream& operator>> (ifstream& ifstr, DWORD& input)

    return ifstr;
