Hi Eli,

Thanks for the suggestion. But it looks like it doesn't solve the problem
completely.

Yes.

I did that and the program compiled fine. But there are still some strange
problems. If I try compiling the same program with <vector> included, I get
errors like this.

#include <curses.h>
#include <vector>

int main ()
{
  return 0;
}

I think I figured out the problem....

curses.h defines a macro by name clear. There is a method called clear in
class ios in strambuf so there's a conflict.

I could put #include <vector> before include curses and that works fine. But
it doesn't sound like a good thing to do. What if I wanted to use the
clear() method of ios? I'll probably compare the curses.h in GNU/Linux and
the one in PDCurses. Lets see...

I guess I'll look into this and see if I can find a solution. In the
meantime if someone has some kind of fix for this, I'd appreciate if you
could send it.

Thanks,
Prashant
