Ok. Mingw *does* have inaddr6_any. Only they have it in the headers,
as an extern, but they didn't put it in their libraries. *sigh*

So one thing we could do is to simply define the extern in a #ifdef
section, right there. Which seems rather ugly. Or we can create a new
symbol on mingw and #define or #ifdef it to use that one, like
inaddr6_any_brokenmingw.

From some googling, the value should be:
static in6_addr inaddr6_any={0,0,0,0, 0,0,0,0, 0,0,0,0, 0,0,0,0};

Which one seems least ugly?
