This problem was reported before several times.  However, none of
those who reported it could describe exactly why does Make fail in
that way, and didn't follow up after I asked them to investigate.
Since I cannot reproduce this problem in machines available to me, I
cannot myself debug it.

It is a known fact that this problem is peculiar to OSR2 and to NTFS
partitions.  I even suspect that the reason is that those filesystems
*round* the current time, rather than *truncating* it, when they
compute DOS file time stamps (which is handled in 2-second
granularity).  But without good understanding of what exactly happens,
I won't even dream of fixing this.

I guess I need to wait until either there are enough people which are
annoyed by this that somebody volunteers to sit down and investigate
the problem, or that I myself get access to one of these systems.
