 As a temporary compatibility measure, it is possible to build the game without requiring boost filesystem or boost locale, using libintl for translations instead. The cost is that wesnoth won't support UTF-8 in filepaths on all platforms.
-For this, target filesystem.cpp and gettext.cpp instead of filesystem_boost.cpp and gettext_boost.cpp. For scons/cmake the "boost filesystem" option toggles these.

 Similarly it is possible, although not recommended, to compile the game with any libsdl-mixer version >= 1.2.0, at the cost of reduced UTF-8 support.
