convert remaining %s to %hs or %ls use WPRINTF_ARGS on unicode printf functions fix: __func__ can't be widened via preprocessor (-> revert to char*) convert remaining external_[directory|file_string to string() Util: don't mix fwprintf and fprintf Formation: fix dangling pointer (storing result of c_str()) This was SVN commit r7164.
