On a VAX, the following program dies horribly under version 1.0:
------------------------------------------------------------------------
#include <stream.h>

main (int argc, char *argv[]) {
	int x = -1;
	cout << hex (x, 8) << "\n";
	}
------------------------------------------------------------------------
The problem is that in ``out.c'' the parameter ``i'' to the ``hex''
function is declared as long, but the conversion loop is a `` do { ...
} while (i>>=4);'' this is an endless loop for negative numbers.
