bitset and CHAR_BIT

[Rainer Dorsch <rainer at rainer dot informatik dot uni-stuttgart dot de>]

I am wondering, why the example of SGI's STL Manual for bitset is not 
compiling with gcc-2.95.1. I get on Linux and Solaris the same error messages.

I included <limits.h> as suggested by http://egcs.cygnus.com/ml/gcc-bugs/1999-0
5/msg00761.html

Does anybody know, what happened?

Thanks.

#include <iostream>
#include <bitset>
using namespace std;

int main() {
  const bitset<12> mask(2730ul); 
  cout << "mask =      " << mask << endl;
  
  bitset<12> x;
  
  cout << "Enter a 12-bit bitset in binary: " << flush;
  if (cin >> x) {
    cout << "x =        " << x << endl;
    cout << "As ulong:  " << x.to_ulong() << endl;
    cout << "And with mask: " << (x & mask) << endl;
    cout << "Or with mask:  " << (x | mask) << endl;
  }
  exit(0);
}

Note, it works with the current STL library of SGI.
