Finally got Google to give a good answer at https://www.archlinux.org/packages/extra/x86_64/wxgtk2.8/files/ (https://www.archlinux.org/packages/extra/x86_64/wxgtk2.8/files/)
I am going with "wx-config-2.8" as the name.
And these for the other names.
usr/share/aclocal/wxwin2.8.m4
usr/share/bakefile/presets/wx28.bkl
usr/share/bakefile/presets/wx28_unix.bkl
usr/share/bakefile/presets/wx28_win32.bkl
Now I have to finish the wxWidgets 2.8 package and start work on the Code::Blocks package.
