2.8.4: * IconTheme: Avoid crash in get_search_path(). Bug #337874, #337875, and #332437. This wins a prize for the most errors in one function. (Jonathon Jongsma, Rob Page, Maxim Udushlivy) * Some code size reduction by using more static functions instead of anonymous namespaces, and by avoiding some code duplication. (Murray Cumming) * Windows Build: - MSVC++ build: Use the new /vd2 compiler option to get the new unbroken dynamic_cast<> with MSVC++. There are now no known problems with the MSVC++ build. Bug #158040. - mingw32 and cygwin builds: Correct some API export/import problems. Bug #309030. (Cedric Gustin, Toralf Lund)
