Not really.  It's quite common that, even when a dependence file is
modified, a generated file that depends on it doesn't change (think of, when the modified hasn't introduced nor
removed any AC_DEFINEs).  In this case, it won't be checked in (unless
someone pushes for it).  Thus, even if CVS were smart enough to retain
relative timestamps globally, it would still get this case wrong.
