C++11/0x/98, problem with wcs case insensitive compare

[SeBeQ]

Hi!

I have Code::Blocks with MinGW with G++ (tdm-1) 4.7.1
I checked option with enable C++11.
I tested auto, nullptr, etc.

If I use
-std=c++98,
-std=c++0x,
-std=c++11

I have error: 'wcscmpi' was not declared in this scope

If I remove any -std=c++[98,0x,11] everything is good/successed

...
return wcscmpi( text1, text2 ) == 0; //Without C++11/0x/98 this is good, but when I enable C11(etc) message say - error: 'wcscmpi' was not declared in this scope

return wcscmp( text1, text2 ) == 0; //case sensitive and previous is good with all -std=c++
...

I try wcscmpi, wcsicmp, _wcscmpi, _wcsicmp with no positive results
also I try add std::, change <cwchar> to <cstring>

Any help?

There's no wcsicmp on the standard.
And anyways, seeing "stricmp" makes me think of "wcsicmp".

Those are WinAPI functions. #include <windows.h>.
