        dnl ****** IMPORTANT *******
        dnl   Unlike for the UNICODE setting, you can build your program in
        dnl   shared mode against a static build of wxWidgets. Thus we have the
        dnl   following option which allows these mixtures. E.g.
        dnl
        dnl      ./configure --disable-shared --with-wxshared
        dnl
        dnl   will build your library in static mode against the first available
        dnl   shared build of wxWidgets.
        dnl
        dnl   Note that's not possible to do the viceversa:
        dnl
        dnl      ./configure --enable-shared --without-wxshared
        dnl
        dnl   Doing so you would try to build your library in shared mode against a static
        dnl   build of wxWidgets. This is not possible (you would mix PIC and non PIC code) !
        dnl   A check for this combination of options is in WX_DETECT_STANDARD_OPTION_VALUES
        dnl   (where we know what 'auto' should be expanded to).
        dnl
        dnl   If you try to build something in ANSI mode against a UNICODE build
        dnl   of wxWidgets or in RELEASE mode against a DEBUG build of wxWidgets,
        dnl   then at best you'll get ton of linking errors !
