Hi All,

We tried to build Mesos on Windows with VS2019. It failed to build due to error C2440 with /std:c++latest on Windows using MSVC. It can be reproduced on latest reversion 97d9a40 on master branch. Could you please take a look at this isssue? Thanks a lot!

Reproduce steps:
# git clone https://github.com/apache/mesos F:\apache\mesos
# Open a VS 2019 x64 command prompt as admin and browse to F:\apache\mesos
# mkdir build_amd64 && pushd build_amd64
# cmake -G "Visual Studio 16 2019" -A x64 -DCMAKE_SYSTEM_VERSION=10.0.18362.0 -DENABLE_LIBEVENT=1 -DHAS_AUTHENTICATION=0 -DPATCHEXE_PATH="F:\tools\gnuwin32\bin" -T host=x64 ..
# set _CL_= /std:c++latest /Zc:char8_t-
# set _CL_= /D_SILENCE_TR1_NAMESPACE_DEPRECATION_WARNING %_CL_%
# msbuild /maxcpucount:4 /p:Platform=x64 /p:Configuration=Debug Mesos.sln /t:Rebuild
