  "message": "ci(windows): build with Rust\n\nThe Windows runners used by Git\u0027s GitHub workflow\u0027s `windows-build` job\nship `rustup` plus a `*-pc-windows-msvc` default toolchain (see\nhttps://github.com/actions/runner-images/blob/main/images/windows/Windows2022-Readme.md\nand\nhttps://github.com/actions/partner-runner-images/blob/main/images/arm-windows-11-image.md),\nbut no precompiled `std` for `*-pc-windows-gnu` or\n`*-pc-windows-gnullvm`. With the Makefile now picking a GCC-compatible\ntarget triple based on `$(MSYSTEM)`, the build step needs that\nprecompiled `std` to be installed before invoking `make`, otherwise\n`cargo build --target \u003ctriple\u003e` fails to find a usable `std` for the\nchosen target.\n\nAdd a step between the SDK setup and the `make` invocation that selects\nthe matching triple from `$MSYSTEM` (which\n`git-for-windows/setup-git-for-windows-sdk` exports for every subsequent\nstep) and runs `rustup target add` for it. The mapping mirrors what\n`config.mak.uname` derives from `$(MSYSTEM)` and `$(HOST_CPU)`, just\nenumerated explicitly here since CI has direct knowledge of which MSYS2\nsubsystems the matrix actually exercises (`CLANGARM64` for the ARM64\nrunner, `MINGW64` for the x86_64 runner). Technically, we only need to\nhandle MINGW64 at present, but the switch to UCRT64 is imminent, and the\nother case arms serve as a very fine documentation of what people should\ndo for other MSYSTEM values.\n\nFor a `staticlib` crate-type `cargo build` does not invoke an external\nlinker, so no further toolchain components (e.g. the `gnullvm` LLVM\nlinker) need to be installed; `rustup target add` alone is sufficient.\n\nAssisted-by: Claude Opus 4.7\nHelped-by: Junio C Hamano \u003cgitster@pobox.com\u003e\nSigned-off-by: Johannes Schindelin \u003cjohannes.schindelin@gmx.de\u003e\nSigned-off-by: Junio C Hamano \u003cgitster@pobox.com\u003e\n",
