Subject: [PATCH] mbcs: Remove lots of global symbols
MBCS has a collection of things that searches say are not used elsewhere
and could be static. If this is the case they should be static, if not
then someone at SGI should rename things like "soft_list" so they don't
pollute the global namespace with generic names...
