And systems like PVCS Dimensions do _not_ properly support timestamps :-)

The scenario is

  check a file out
  modify it and compile
  decide to revert; fetch original file contents *and revert to original
    timestamp*
  'make' doesn't see it needs to recompile the file

(well, actually, GNAT (gnatmake) isn't affected because it compares
timestamps for equality)
