67 support arbitrary combinations of libs/DLLs: either we build all of them as
68 DLLs (in which case WXMAKINGDLL is defined) or none (it isn't).

70 However we have a problem because we need separate WXDLLEXPORT versions for
71 different libraries as, for example, wxString class should be dllexported
72 when compiled in wxBase and dllimported otherwise, so we do define separate
73 WXMAKING/USINGDLL_XYZ constants for each component XYZ.
