             Summary: Compile failures with char8_t by MSVC under /std:c++latest mode
                 Key: MESOS-9718
                 URL: https://issues.apache.org/jira/browse/MESOS-9718
             Project: Mesos
          Issue Type: Bug
          Components: build
            Reporter: QuellaZhang


Hi All,

We've stumbled across some build failures in Mesos after implementing support for char8_t under /std:c++latest in the development version of Visual C++. Could you help look at this? Thanks in advance! Noted that this issue only found when compiles with unreleased vctoolset, that next release of MSVC will have this behavior.

*Repro steps:*
git clone -c core.autocrlf=true https://github.com/apache/mesos D:\mesos\src
open a VS 2017 x64 command prompt as admin and browse to D:\mesos
set _CL_=/std:c++latest
cd src
.\bootstrap.bat
cd ..
mkdir build_x64 && pushd build_x64
cmake ..\src -G "Visual Studio 15 2017 Win64" -DCMAKE_SYSTEM_VERSION=10.0.17134.0 -DENABLE_LIBEVENT=1 -DHAS_AUTHENTICATION=0 -DPATCHEXE_PATH="C:\gnuwin32\bin" -T host=x64
