Currently, the install scripts are using a very old build of mingw from sourceforge with gcc 8.1.0 but v6 of the mingw runtime (from 2018). There is a build here with gcc 8.5.0: https://github.com/niXman/mingw-builds-binaries/releases/tag/8.5.0-rt_v10-rev0. This version is much more up to date with features in windows headers that have been added since 2018.

@tobil4sk - Thank you for bringing this issue to us. We are investigating on this issue , and will get back to you after our findings.

@tobil4sk - We don't want to switch to new installation method because we have concerns about supply chain when we use unofficial build of mingw.

And we prefer to keep using official build distributed via sourceforge even if it is outdated.

Thank you, I am closing the issue.
