I did keep digging for quite a while, but didn't manage to get to the
bottom of it.  In the end I worked round the problem by adding code to
compare the value of counts->updating in make.c with the value of
counts->made in make1.c, and if there's an underbuild then spawn jam
again with the same arguments.  It's pretty nasty, but it works.

Sorry I didn't have the time to fix this properly :-(.
