  Is there still a problem with the skipws formatting flag in the latest
version of DJGPP?  I have searched high and low for an answer to this
problem with no luck.  I was convinced that I had finally found it here:

1:16:09, but it was another dead end, as Horst Kraemer suggested the use of
a statement opposite to what I suspect Mr. Derbyshire was _really_ after
(whitespace skipping is ON by default - I want to turn it OFF).  For
example, the following snippet does not behave as it should under v2.95.2,
although it works fine with TurboC++ v3.0:

#include <iostream>
void main(void)
{
   int i;
   cin.unsetf(ios::skipws);  /*DO NOT ignore whitespace*/
   cin >> i;
   if (cin.good())
      cout << "OK\n";
   else
      cout << "ERROR\n";
}

  When the user enters leading whitespace or even just Enter without any
input, it should set "failbit" in the stream error-status flags, thus
causing cin.good() to fail and print "ERROR".  It doesn't.  The cursor just
drops down a line and waits for input -- as it normally does by default.
Has this bug been addressed?

Thanks in advance for any info. :-)
