I do not know how to fix the execution problem.  For my gcc 3.0
(~May22), the problem seems to be trying to change cout's stream
buffer.  If the debugger is not lying, unit.cc's putsetbuf() is
invoking std_streambuf's setbuf(), which does nothing.  I do not like
the design choice, but the published interface makes changing it
beyond my ability to think of another approach.
