It seems to happen especially with prerequisites created by `touch`: e.g.:
$ cat Makefile all : bar baz
bar baz : foo cp $< $@
foo : touch $@
$ rm foo bar baz $ make touch foo cp foo bar cp foo baz $ make cp foo bar cp foo baz $ make cp foo bar cp foo baz $ make cp foo bar cp foo baz $ make cp foo bar cp foo baz $ make cp foo bar $ make make: Nothing to be done for `all'.

It knows by lesser time precision (exactly 2 sec).
Try example on NTFS.
