-If you checked your sources from version control repository and didn't
-obtain them from a release file, you may need to update your
-`include/wx/msw/setup.h` file to add any new options from
-`include/wx/msw/setup0.h` to it. If you hadn't edited `setup.h` file
-manually, you can just delete it to force recreating it by copying
-`setup0.h` to `setup.h` during the next build. If you forget to do it,
-you may get errors during the build due to new options being
-undefined.
-
-If you have no intention of ever modifying `setup.h`, you may avoid this
-problem entirely by creating a symbolic link to `setup0.h` before
-building, e.g. using mklink, from an admin command prompt:
-
-    cd %WXWIN%\include\wx\msw\
-    mklink setup.h setup0.h
