<listitem>
<para>This ensures that Ncurses does not build support for the Ada

<term><parameter>--enable-widec</parameter></term>
<listitem>
<para>This switch causes wide-character libraries (e.g., <filename
class="libraryfile">libncursesw.so.&ncurses-version;</filename>)
to be built instead of normal ones (e.g., <filename
class="libraryfile">libncurses.so.&ncurses-version;</filename>).
These wide-character libraries are usable in both multibyte and
traditional 8-bit locales, while normal libraries work properly
only in 8-bit locales. Wide-character and normal libraries are
source-compatible, but not binary-compatible.</para>
