Wrong/ inconsistent responses from diff

Not quite. Still with cygwin v.1.6 but having reverted to diffutils 
v.2.8.7-2 I'm still getting weird responses (though many fewer). The two 
directories explored below have identical contents, not the 3 
differences identified:

~> diff -rq /home /l/home
Files /home/user/sav/bookmarks.html and /l/home/user/sav/bookmarks.html 
differ
Files /home/user/sav/userTheme.Theme and 
/l/home/user/sav/userTheme.Theme differ
Files /home/user/tex/short-math-guide.pdf and 
/l/home/user/tex/short-math-guide.pdf differ
~>
~> diff -rq /m/home /l/home
~>

If this strange behaviour is not due to recent upgrades of diffutils, 
then the only other relevant change is possibly to cygwin1.dll.

I have not gone through airport security with my machine, X-rayed it or 
dropped it in a magnetic field resonator, though I agree this behaviour 
is suggestive of any or all of these!
