138 <para>This switch causes wide-character libraries (e.g., <filename

140 to be built instead of normal ones (e.g., <filename
141 class="libraryfile">libncurses.so.&ncurses-version;</filename>).
142 These wide-character libraries are usable in both multibyte and
143 traditional 8-bit locales, while normal libraries work properly
144 only in 8-bit locales. Wide-character and normal libraries are
145 source-compatible, but not binary-compatible.</para>

195 compatible with <filename>libncurses.so</filename> and the
196 wide-character definition is compatible with
197 <filename>libncursesw.so</filename>. Since we are using
198 <filename>libncursesw.so</filename> as a replacement of
199 <filename>libncurses.so</filename>, edit the header file so it
200 will always use the wide-character data structure definition
