Yay!  Good one.  The quote Tom gave was not in the C99 draft I have access
to, and the 1998 C++ standard only contains a footnote implying that the C
standard at the time _did_ allow overlap of function calls whose order is
not specified.  But what you quote here (apart from the "Proposed")
implies that C89 makes the guarantees we need.
