1).
please don't close this issue as invalid - orignal topic is fixed on 4.7.
will it be backported to 4.6? (i have an adjusted patch).
2).
i've found the core issue for problem mentioned in comment 12.
the --disable-nls configure option causes missing x64 .dll exports
but this is imho a bug (libstdc++ headers allow boost to use locale
support but linking fails later). i've --enabled-nls and it works fine.
