This is a weird problem.  Caused by interaction of cygwin 1.7 and 
Perfect Disk 7.0 (defragmeter).

A couple of days ago, I was defragmenting my drive C: when I discovered 
a copy of every cygwin's file with a naming convention of: 
AY63D92E~orig.file.name~.  The leading chars were 8 letters/numbers of 
uppercase.  The filename portion surrounded by the "~" character.  This 
happened only under the /cygwin tree while the MS-DOS (Win XP Pro) were 
unaffected.

All of these files were "copies" of cygwin's files (link count == 1).  
Now that Perfect Disk 7.0 is done with drive C:, I'm going to delete all 
47,000 of these burgers.

This a weird interaction between 1.7 and Perfect Disk.  The problem 
stopped happening when Perfect Disk finished with drive C:.  This is 
"far" from a feature, a definite bug.

One thing to note:  The mtimes of all of the duplicate files were 
current.  They did not reflect the mtime of the original file.
