Well, here you are more lucky ;) Maybe we are slightly off-topic,
however, because this list is about libstdc++-v3 development... Anyway,
we can abuse it a bit, during the weekend... ;)

I don't think passing --disable-c-mbchar is the way to go, because
effectively disables wchar_t, that you want, although in the *special*
2-bytes form. Which kind of problems are you having with basic_string?
Shouldn't work too bad together with -fshort-wchar...
