There is a left manipulator defined in the standard, but it is not yet
implemented in GCC.

As a workaround, it is possible to define your own version:

/* ------------------------------------------------ */
#include <iostream>
#include <iomanip>
using namespace std;

ios& left(ios& i)
{ i.setf(ios::left, ios::adjustfield); return i; }

int main()
{
    cout << left << setw(50) << "Hello world";
}
/* ------------------------------------------------ */

Missing features of <iomanip> have been reported here before.  But
DJGPP does not provide the C++ implementation so these problems should
be reported to the relevant GCC group.

Given the fundamental nature of the problems, (and the apparently easy
fix), it is probably already being worked on.  If you ask in a GCC
group you might get some some idea of when these features will be
implemented.
