At the moment I've no Windows system to test it, but the error might be
caused by a missing export statement.

In execution_context_v1.hpp change the code to:

struct BOOST_CONTEXT_DECL activation_record ...
struct BOOST_CONTEXT_DECL activation_record_initializer ...

Boost 1.60 doesn't have that file.  But making those changes in
execution_context.ipp causes the errors mentioned in
https://svn.boost.org/trac/boost/ticket/11365 ie. being incompatible
with thread_local (thread locals need to be behind a pimpl wall; they
can't be exported directly).

I'm about to try updating to 1.63 anyway, so we'll see how that goes, I
guess.

Good news: looks like this isn't an issue any more with Boost 1.63.  My
apologies for the noise.

Although now I have a related-but-different problem.

        typedef boost::coroutines2::coroutine<void>::push_type coroutine;

        std::vector<coroutine> coros;
        coros.emplace_back(std::bind(std::forward<F>(f), i, std::placeholders::_1));
        // where f is a template functor&& and i is a template iterator

This code compiles fine in:
  - VS2013 (Windows, Boost 1.55, coroutines1)
  - VS2015 (Windows, Boost 1.55, coroutines1)
  - GCC 4.8.2 (Linux, Boost 1.55, coroutines1)
  - VS2015 (Windows, Boost 1.63, coroutines1 & coroutines2)
  - GCC 4.8.2 (Linux, Boost 1.63, coroutines1)

But using GCC with Boost 1.63 and coroutines2 I get some quite verbose errors that I'm having trouble making sense of.  (Clang 3.4 gives a similar error.)  Is this a bug or am I doing something weird?
