620 dnl Unlike for the UNICODE setting, you can build your program in

623 dnl
624 dnl ./configure --disable-shared --with-wxshared
625 dnl
626 dnl will build your library in static mode against the first available

632 dnl
633 dnl Doing so you would try to build your library in shared mode against a static
634 dnl build of wxWidgets. This is not possible (you would mix PIC and non PIC code) !
