[Mingw-cross-env-list] Problem cross compiling with -std=c++0x

[Lothar May]

Hi,

I'm having trouble cross compiling with the -std=c++0x option. Now I
have a small test case which clearly shows the problem:

-- cut here --
#ifndef WIN32
        #error Define is missing!
#endif

int
main()
{
        return 0;
}

-- cut here --

I pasted the upper code into cpp0x.cpp. Running
i686-pc-mingw32-g++ cpp0x.cpp
is fine, but running
i686-pc-mingw32-g++ -std=c++0x cpp0x.cpp
leads to the error "Define is missing!"

Does anyone know what can be done about this?

Regards,
Lothar
