The first of these is probably redundant, and the second might install
more than required. Here's my recipe for what I use in testing patches
with MSVC:


choco install -y --no-progress --limit-output
visualstudio2019-workload-vctools --install-args="--add
Microsoft.VisualStudio.Component.VC.CLI.Support"


That gives you the normal command line compilers. After that these
packages are installed:


vcredist140 14.29.30037
visualstudio-installer 2.0.1
visualstudio2019-workload-vctools 1.0.1
visualstudio2019buildtools 16.10.1.0

A simpler alternative is just to rename the chocolatey shims. Here's a
ps1 fragment I use:


    $cbin = "c:\ProgramData\chocolatey\bin"
    Rename-Item -Path $cbin\win_bison.exe -NewName bison.exe
    Rename-Item -Path $cbin\win_flex.exe -NewName flex.exe
