If _WIN32_WINNT is unset, we force it to a new enough value to make sure the necessary definitions are visible. When targeting Windows Phone or Windows RT, _WIN32_WINNT should be at least 0x0602 - otherwise the windows headers themselves can cause errors (which technically are bugs in the headers). Raising this value here shouldn't hurt; the alternative would be to not touch it at all if WINAPI_FAMILY is set to phone/app, or to force setting it to 0x0602 in configure if unset (for phone/app).
