The following used to work, but now does not: diff -q --to-file=old foo.tex bar.tex
where old is a sub-directory of the current directory. This always reports: diff: old: No such file or directory It's ok when only one file is listed: diff -q --to-file=old foo.tex cygcheck -c diffutils indicates version 3.12-1. cygwin is 3.6.3-1 Let me know if there is more info I can offer.
