1. Clearly document the wxDL_XXX macros; including their implicit usage of m_ok member variable 2. Made sure they're used in the same way in all places they are used (sometimes they were passed an object, sometimes a pointer, breaking compilation: see patch 1791288) 3. Don't allocate wxDynamicLibrary objects on heap unnecessarily (which removes the need to delete -- or leak, as it was -- them afterwards) 4. Some naming convention fixes git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@48625 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
