Une autre solution, c'est d'utiliser WriteConsoleW() au lieu de wcout et cie. Le problème, c'est que tu perds la possibilité de rediriger la sortie de ton programme vers un fichier.

   std::cout<<"ascii"<<std::endl;
    return 0;
}

Compile sans problème chez moi. J'ai mingw 4.3.3 (TDM Builds)

     }
  }
}

pour un changement de nom de fichier on récupère FILE_ACTION_RENAMED_OLD_NAME mais pas FILE_ACTION_RENAMED_NEW_NAME
Le probleme vient des lignes suivantes:

p_cur = reinterpret_cast<FILE_NOTIFY_INFORMATION*>(reinterpret_cast<unsigned char*>(p_cur) + p_cur->NextEntryOffset);
}while(p_cur->NextEntryOffset>0);

Il faut plutot mettre

bool bHasNextEntry = false;

do
{
// ....
bHasNextEntry = p_cur->NextEntryOffset>0;
p_cur = reinterpret_cast<FILE_NOTIFY_INFORMATION*>(reinterpret_cast<unsigned char*>(p_cur) + p_cur->NextEntryOffset);
}while(bHasNextEntry);
