----------------------------------
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.

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"
