Ultimately, if this is a real issue in practice, the solution would be a
gnulib module that provides waitpid replacements for lacking systems.  But
most likely, nobody actively ports to those old platforms any more.  Also,
gnulib already has a wait-process module, so I wonder if it would be
useful here.
