Subject: [PATCH] Include wchar.h so that mbstate_t is available in global
 namespace. Maybe, I should revert the last patch, which made the file use
 ::mbstate_t as opposed to std::mbstate_t, but I'm waiting for Pavel to tell
 why it was necessary to use ::mbstate_t and if this version of borland can be
 made to work in some other way.
