Hi, all!  I am having trouble compiling c++ source after reinstalling
my system.  To show the error, I chose a simple old example.

I have djgpp installed in e:\djgpp.  I am passing the compilation
parameter -lgpp, but I am getting unresolvced references of cin and
cout.  I am sure I am just missing something basic, but I went over
the steps in the faq and everything still seems to be in order, but
not working.  Any suggestions? (email or news is fine)

code:------------------------------------------
// myfirst.cpp--displays a message
#include <iostream.h>	// a PREPROCESSOR directive
int main(void)
{
	cout << "Come up and C++ me some time.";
	cout << "\n";
	return 0;
}
