Hi,

But this change is incorrect.  It canmcels the whole trick:

        touch tmp
        ...
        mv tmp $@

ensures that the stamp file will be older than the files created by
"...".

If the rule were:
        ...
        touch $@
then each make would rebuild the files, with new stamp.

Though with your code it doesn't happen always, the problem is still there.
