<complex> and <string> must be #included before STL.

I found this out in a huge program and couldn't find the bug so I made
a copy and started deleting stuff to see when the bug would go away. I
eventually got to this, and the bug was still there:

#include <list>
#include <complex>
#include <string>

So I rearranged the includes

#include <complex>
#include <string>
#include <list>

and the bug went away.

I didn't see this in the FAQ or the INFO anywhere. Maybe I missed it.
But to make this less of a problem for others, I recommend not only
that the information be added if it is not present, but that something
like these lines be added to the beginnings of CINST.H and SINST.H:

#ifdef FUNCTION_H
#error Include this file before STL!
#endif

The full path, by the way, is \DJGPP\LANG\CXX\STD\ for both files.

This will replace a bunch of obscure errors with something more
obvious.

Including function.h first caused more headaches than I care to
recount.

I hope no one ever has these particular headaches again.
