The bootstrap of Emacs on Cygwin is broken [Is also: unicode branch is merged to trunk]

[Angelo Graziosi]

After the unicode branch is merged to trunk, bootstrapping Emacs on
Cygwin fails as reported below. The bootstrap was configured as follow:


    LDFLAGS='-Wl,--enable-auto-import -Wl,--enable-auto-image-base' \
    ../configure --prefix=${prefix_dir} \
                 --with-x-toolkit=lucid

(I have used the same build scrip with which I bootstrap Emacs since
an year and more).

Emacs-CVS of less than 24 hours ago bootstraps just fine!
