I have installed djgpp 1.12m4 (and am an experienced C programmer using
it).
I decided to try out C++, since we are going to be using it to teach
students next year.  I seem to have immediate problems as soon as I use
manipulators in the output stream.  I would have thought that I have
done something gross as pat of the installation, but I can't think what!
Could some kind reader enlighten me?

The failing program and teh compiler output when using gcc -v is appended.

// failure of setw in the output stream
#include <iostream.h>
#include <iomanip.h>

main()
{
  int j = 735;
  cout << j << setw(4) <<j <<endl;
}


Output from
	gcc -v fail.cc -o fail -lgpp
