57 We support building wxWindows as a set of several libraries but we don't
58 support arbitrary combinations of libs/DLLs: either we build all of them as
59 DLLs (in which case WXMAKINGDLL is defined) or none (it isn't).
60
61 However we have a problem because we need separate WXDLLEXPORT versions for
62 different libraries as, for example, wxString class should be dllexported
63 when compiled in wxBase and dllimported otherwise, so we do define separate
64 WXMAKING/USINGDLL_XYZ constants for each component XYZ.
