[gdal-dev] Building with recent versions of Visual Studio 2019 fails due to cstdint problems C2039 C2873 

[Millman, Mark]

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 cstdint 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 OPTFLAGS but I get the same results.

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

Thank you -- Mark Millman
