  Indeed, this does fix the problem. Does this mean that pch still
does not inherit the requirements of its parent target (in this case
hello executable)?

  There is still the problem with pch that sometimes the source that
creates the precompiled header file is compiled with incorrect
commands (please see
http://article.gmane.org/gmane.comp.lib.boost.build/14061).
  Franz Schnyder suggested a patch to msvc.jam that fixes the problem,
and I am attaching a slighltly modified version of his patch that is
made against the current CVS head.
