boost-libs broken on -current (exceptions again?)

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Is boost-libs building for anyone on -current?

I've tried on 6.99.47 with both clang and gcc (in both cases starting
a bulk build without any existing binary packages, independently for
clang and gcc), and it failed building with many errors, some of them
are:

./boost/serialization/throw_exception.hpp: In function 'void 
boost::serialization::throw_exception(const std::exception&)':
./boost/serialization/throw_exception.hpp:30:5: error: 'throw_exception' is not 
a member of 'boost'
     ::boost::throw_exception(e);
     ^



./boost/serialization/throw_exception.hpp:29:44: error: variable or field

 inline void throw_exception(std::exception const & e) {
                                            ^
./boost/serialization/throw_exception.hpp:29:29: error: 'exception' is not a

         ^

The first two of these remind me of the C++ programs that don't work
any longer (see my previous post to this list).
