I've been building GDAL for the last 8 years or so for almost every new release. And I successfully built version 2.4.1 with Visual Studio 2019 when it first came out. However, I am no longer able to build V2.4.1 or V3.0.4 or V3.1.0 with the latest releases
of Visual Studio 2019. I get error C2039 and C2873 indicating a conflict with<span> </span><i style="font-weight:bold">cstdint</i> and the global namespace. I've installed fresh copies of Visual Studio and replicated the issue on three different machines.
I have tried adding both /std:c++14 and /std:c++17 switches to <b>OPTFLAGS</b><span> </span>but I get the same results.</div>

Has anyone else successfully built GDAL with VS 2019 (V16.5.4 or higher)? Can anyone offer any suggestions?</div>
