Subject: Re:  [3.4 Regression] unget does not work

(Independently arrived at this, thus I concur with the rename
 and critical upgrade...)

#include <iostream>
#include <testsuite_hooks.h>

// Derived from libstdc++/12048 by LJR.  Exercise for the reader to
// figure out how to get this interactive test into our dejagnu...
// Rewriting the test to use an opened fstream displays no failure...

int main()
{
  bool test = true;
  char c1;
  char c2;
  std::cin.get(c1);
  std::cin.unget();
  std::cin.get(c2);
  VERIFY (c1 == c2);
}
