To learn more, run the command again with --verbose.

I cannot test *-msvc since trying to use rust's msvc target will require installing msvc build tools and does not work inside a msys2 shell because cargo tries to use GNU link rather than the one from msvc and it seems installing the 5GB msvc build tools inside a VM doesn't work either since it errors out on LINK : fatal error LNK1181: cannot open input file 'advapi32.lib' from the x64 Native Tools Command Prompt for VS 2019 after setting the proper toolchain.

running cargo build from stable-x86_64-unknown-linux-gnu works fine.

Run git pull and cargo update. This error has been fixed in the latest version (2.11.1).

Thanks, although the warnings are still there, it no longer errors out and compiles successfully
