(SOLVED) g++ compiler error on iostream method .flags()

Hello, I'm trying to compile some code that uses a C++ ostream method called .flags().

This is a simple version of what the code is doing, and where the problem occurs.

#include <iostream>
#include <iomanip>
long originalformat = output_stream.flags(); // saves original format
// ...various other code
output_stream.flags(originalformat); // reset flags
The error happens on the last line where I try to set the output_stream's flags to the original value. I am using G++ version 4.1.2. Here is the compiler output error:

error: invalid conversion from 'long int' to 'std::_Ios_Fmtflags'
error: initializing argument 1 of 'std::_Ios_Fmtflags std::ios_base::flags(std::_Ios

The type you should use in not long, but ios_base::fmtflags.
