sorry to jump in, but I think linux from scratch has libncurses.so pointing to
libncursesw.so. Exactly, they do:
for lib in ncurses form panel menu ; do
    rm -vf                    /usr/lib/lib${lib}.so
    echo "INPUT(-l${lib}w)" > /usr/lib/lib${lib}.so
    ln -sfv ${lib}w.pc        /usr/lib/pkgconfig/${lib}.pc
done
So libncurses.so is a linker script, and passing -lncurses is equivalent to
passing -lncursesw.

Now, whether krb5 configure should use a different method is another story.
