Boost failed with error C2892 when build with MSVC on windows

Hi All,

We tried to build and run hof test for Boost with VS2017 Update 7 on Windows. It failed to build due to the error C2892. Could you please help take a look at this? Thank you!

**Reproduce steps:**

1. git clone -c core.autocrlf=true --recursive https://github.com/boostorg/boost.git D:\Boost\src
2. open a VS 2015 x86 command prompt and browse to D:\Boost\src
3. .\bootstrap
4. .\b2 headers variant=release --build-dir=..\out\x86rel address-model=32
5. .\b2 variant=release --build-dir=..\out\x86rel address-model=32
6. .\b2 -j4 variant=release --build-dir=..\out\x86rel libs\hof\test

**Failures:**
