Hash: SHA1

At one point in the distant past
(http://sourceware.org/ml/cygwin/2002-04/msg01648.html), the hash
algorithm was very weak on strings differing only in the suffix (a common
feature of pathnames) (if I recall correctly,
d:\cygwin\tmp\classpath\java\n{et,io} clashed on my win98 box), and I
submitted a patch to improve it. I think a different hash is in use
today, but it is likewise strong enough for every file I've run across.
The other weirdness is that on FAT and other file systems that don't
support hard links, link() is faked by producing copies, which no longer
have unique inodes, so maybe that is part of the problem.
