```

Start with build.yaml and build-boringssl.ps1, then inspect the linked Windows Actions run and the BoringSSL failure at crypto/bio/connect.c:488. Reproduce the Windows 2022 build using the pinned BoringSSL revision and the shown CMake/MSBuild commands. Done means the workflow builds BoringSSL and lsquic successfully without the warning being treated as an error.
