  This has gotten worse over the past couple of months; I fixed it on cygwin a
while ago by turning up the stack size, finding that it needed somewhere
between 10MB and 12MB on that target; now it's just started failing again.

  I don't know at what point we should consider this a compile-time performance
regression.  Paolo, even a 30% reduction seems like a good idea to me; why not
submit that patch you developed?
