FWIW, I cannot reproduce this on MS-Windows with Emacs 23.3.  I don't
have Exuberant CTags, but using the etags program provided with
Emacs.  I get relative file names with either method.

Can you reproduce the problem in "emacs -Q"?  If not, there's some
customization of yours that causes this, or maybe it is a problem with
Exuberant on Windows.
