  "message": "PR #2172: Treat clang targeting Windows as a MinGW compiler\n\nImported from GitHub PR https://github.com/abseil/abseil-cpp/pull/2172\n\nClang targeting `*-w64-windows-gnu`, e.g. via the hermetic LLVM toolchains from the `llvm` Bazel module, reports `@bazel_tools//tools/cpp:compiler` as `clang` rather than `mingw-gcc`. The `//absl:mingw_compiler` condition therefore doesn\u0027t match and the `-l\u003clib\u003e` flags for system libraries are missing, since only the `-DEFAULTLIB:\u003clib\u003e.lib` variants (which the GCC-style driver silently ignores) are passed:\n\n```\nld.lld: error: undefined symbol: BCryptGenRandom\n\u003e\u003e\u003e referenced by external/abseil-cpp+/absl/random/internal/_objs/seed_material/seed_material.pic.o\n```\n\nThis adds a `mingw-clang_compiler` setting that matches `clang` on Windows and includes it in `mingw_compiler`. `clang-cl` is unaffected since it reports itself as `clang-cl`.\n\nFound while cross-compiling Bazel itself to Windows.\n\nMerge 573fe91cb0aa18e79870347b1feb1176e33cf444 into ac102851b3f2a8c8275a0afb764082a0d5b09fa1\n\nMerging this change closes #2172\n\nPiperOrigin-RevId: 988758643\nChange-Id: Icf3e79e7ed3d17f6bd0f9fbbedc51620b07bed7c\n",
