I don't know whether the -d is important, and I'm pretty much both -1
and -d are portable. Actually, I learned this means to compute the
most recent file from Alexandre Oliva, who is an extremely careful
portable shell script author. He has included this is his still born
AdHoC (which M4sh is supposed to replace).
autoreconf used to use it too, when it was written in shell script.
