setup.hints which mention Base in their category

[Christopher Faylor <cgf-use-the-mailinglist-please at cygwin dot com>]

The discussion in the cygwin list got me wondering if we had had creepage
into the Base category so, since grep is my friend, I came up with this
list:

alternatives/setup.hint                 gzip/setup.hint
ash/setup.hint                          login/setup.hint
base-files/setup.hint                   man/setup.hint
base-passwd/setup.hint                  ncurses/libncurses5/setup.hint
bash/setup.hint                         ncurses/libncurses6/setup.hint
brltty/setup.hint                       ncurses/libncurses7/setup.hint
coreutils/setup.hint                    ncurses/libncurses8/setup.hint
cygwin-doc/setup.hint                   ncurses/setup.hint
cygwin/setup.hint                       readline/libreadline4/setup.hint
diffutils/setup.hint                    readline/libreadline5/setup.hint
editrights/setup.hint                   readline/libreadline6/setup.hint
findutils/setup.hint                    rebase/setup.hint
gawk/setup.hint                         run/setup.hint
gdbm/libgdbm-devel/setup.hint           sed/setup.hint
gdbm/libgdbm/setup.hint                 tar/setup.hint
gdbm/libgdbm3/setup.hint                termcap/setup.hint
gdbm/libgdbm4/setup.hint                terminfo/setup.hint
gdbm/setup.hint                         which/setup.hint
grep/setup.hint                         zlib/setup.hint


(I obviously could have gotten this from setup.ini, too)

So the question is: Does this list look right.  I'm not sure about
brltty and gdbm.  And I also wonder about ncurses, readline, and zlib.
While they probably do get used by default anyway, I wonder why they
have to be in Base.  Is there a broken dependency somewhere?  If not, it
seems like they would be loaded automatically by anything in Base which
needed them.
