Issue description:
One test fails to compile after boostorg/coroutine submodule updated from d698d1 to d5e610 boost/coroutine@49c1730. Could you please take a look?

log_x64_test_124.log

Reproduce steps:

1. git clone -c core.autocrlf=true --recursive ​https://github.com/boostorg/boost.git D:\Boost\src
2. open a VS 2017 x64 command prompt and browse to D:\Boost\src
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=..\out\x64rel address-model=64
5. .\b2 variant=release --build-dir=..\out\x64rel address-model=64
6. .\b2 -j4 variant=release --build-dir=..\out\x64rel libs\beast\test

Maybe it is caused by commit a3e511f - could you revert it and test it again?

Also affects icinga2 via Boost.Asio. Reverting a3e511feb964 does help.
