boost breakage?

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

Before lunch, my code compiled. I ran a pkg_rolling-replace over
lunch, which updated boost to 1.57.0(nb1 for headers). Now the same
file, no changes, fails to compile with:

In file included from /usr/pkg/include/boost/asio.hpp:20:
In file included from /usr/pkg/include/boost/asio/associated_allocator.hpp:18:
In file included from /usr/pkg/include/boost/asio/detail/config.hpp:26:
In file included from /usr/pkg/include/boost/config.hpp:61:
/usr/pkg/include/boost/config/detail/suffix.hpp:510:26: error: __float128 is not
      supported on this target
   __extension__ typedef __float128 float128_type;
                         ^

?!

Cheers,
