Hi Dave -- I had this on my list of things to look into, in fact.

I've ruled out lang-f77 as a candidate for this problem, because
the important attribute of lang-f77 is its *existence* as a file,
not is date-time information.  It's used as a convenient flag,
nothing much else.

But other uses of `touch' to update makefile-related targets
could be profitably changed to `echo timestamp > '.  So I'll
resume looking for such cases in g77 build procedures at some
point.
