dolphin/Externals/wxWidgets3/include/wx/mstream.h
Soren Jorvang d14efe561b Import r67258 of the wxWidgets trunk, which I expect will before
long become wxWidgets 2.9.2, which in turn is expected to be the
last 2.9 release before the 3.0 stable release.

Since the full wxWidgets distribution is rather large, I have
imported only the parts that we use, on a subdirectory basis:

include/wx/aui
include/wx/cocoa
include/wx/generic
include/wx/gtk
include/wx/meta
