I have just moved an backup version of a file in an compilation tree
over the orignal:
mv backup.c~ backup.c
That's nothing special of course. However the interresting thing
was that make didn't notice this at all. In esp. it didnt notice this
as a change to backup.c and didn't therefore any recompilation work.
I would suspect that in this case the modification time of the
inode corresponding to backup.c~ didn't get updated.
Is this correct behaviour?
