To summarize:

#include <iostream>

int main (void)
{
      cout <<"Hello world!\n";

return 0;
 }

This appears to work great. However I'm more than a little puzzled as to why I even had
to ask this question. I got all my advice about writing a sample program from two or
three books about C++, none of which even mentioned any of this advice you are talking
about. I also remember using rhide to build hello.exe without these changes. Is this
because djgpp is just being more exact about the syntax ? Are these books somehow out of
date ?
