du can only report what the OS tells it.  If it shows increasing numbers,
then it was very likely that some process was consuming disk space in that
directory (in spite of your claims to the contrary).

"Not quite" is an understatement - cygwin is at 1.5.18; your version is
missing a year and a half of bug fixes.

Browse the archives of the cygwin-announce list to see relevant changes
announced for each software upgrade (for this email, that would include
searching for mail with cygwin or coreutils in the subject):
http://cygwin.com/ml/cygwin-announce/

For particular programs, you can often find an online repository of
changes.  For example, cygwin changes are tracked here:
http://cygwin.com/cgi-bin/cvsweb.cgi/src/winsup/cygwin/ChangeLog?cvsroot=src

And many programs maintain a condensed version of user-visible changes.
For example, coreutils changes that have happened since sh-utils,
fileutils, and textutils here:
http://cvs.savannah.gnu.org/viewcvs/coreutils/NEWS?rev=1.354&root=coreutils&view=markup

Google can be your friend, after all.
