OMG.  In this case, it might be safer to change the code again to make 
it actually use the ctor variant it used before (char const * and Locale 
const &).  Matúš, can you check whether the attached 
0001-Rewrite-fix-to-use-the-same-SimpleResMgr-ctor-as-it-.patch would be 
sufficiently unambiguous for MSVC?
