Boost coroutine needs an inline declaration for one of the template specializations to avoid linking errors.

[benkerby@…]

In the file: coroutine/asymmetric_coroutine.hpp (line 1612) there is a constructor for a specialization of push_coroutine< void > that is neither templated nor marked as inline. This can cause linking errors if the constructor is called in multiple translation units.

It should read:

inline push_coroutine< void >::push_coroutine(coroutine_fn fn, attributes const& attrs)

Note that this is only defined if BOOST_MSVC is defined (i.e. is only a problem when using Visual Studio.
