This direct `%clang-resource-dir` check does not work for `-###` output on Windows. The substitution gives a raw path like `C:\...\clang\23`, but `-###` prints escaped paths like `C:\\...\\clang\\23\\include`. Could we capture `RESOURCE_DIR` from the `"-resource-dir"` argument in this output and reuse it for the include path check? That should work for both Windows and Linux.
