Can't compile LE on MinGW (std::wifstream issue)

Hi, I can't compile the Layout Editor on Windows using MinGW 4.4.1 and Ogre 1.7.1 with MyGUI-SVN (Revision: 3397) on Windows 7 (both x86 and x64).
I get an error message about std::wifstream.open() not accepting the wchar_t but requiring a const char* instead.

Compiler Output:
[ 73%] Building CXX object Tools/LayoutEditor/CMakeFiles/LayoutEditor.dir/Application.cpp.obj
D:\MyGui\mygui-r3397\Tools\LayoutEditor\Application.cpp: In member function 'virtual void tools::Application::prepare()':

The error has been there for a while.

I hope this can be fixed.

Thank you. You should've reported earlier if you seen that before. It's pretty easy to fix, but neither me nor my.name use MinGW, I only run it from time to time to test.

Fixed.

That was fast! I'll test it now. And if I encounter any more bugs I'll let you know as soon as I find them in future.

Thanks
