The config system shouldn't make that assumption; we explicitly set
_NATIVE_WCHAR_T_DEFINED when we turn on wide character support.

The code which handles it is:

    # tell the compiler about the base toolset.
    if $(INTEL_BASE_MSVC_TOOLSET) = msvc
    {
        C++FLAGS += /Qvc6 ;
        # no wchar_t support in vc6 dinkum library.
    }
    else
    {
        if $(version) > 5
        {
            # Add support for wchar_t
            C++FLAGS += /Zc:wchar_t
              # Tell the dinkumware library about it.
              -D_NATIVE_WCHAR_T_DEFINED
              ;
        }

        C++FLAGS += /Q$(INTEL_BASE_MSVC_TOOLSET) ;
    }

If your installation path for the compiler includes a "CompilerXX"
element, where XX is a two-digit number, it will deduce the version
from that.  Otherwise, you should set INTEL_VERSION to a one digit
number, "7" in your case.  Note that if you installed Intel to use
msvc6 as its back-end toolset, you won't get wchar_t support either
because the standard library can't handle it.
