REM Build the BackstageInjection DLL for Windows x64 using cargo (GNU target).
REM The GNU toolchain is required: the reflective loader manually maps the image
REM without the MSVC CRT bootstrapping, and the MSVC CRT's TLS/CFG machinery
REM fast-fails (0xC0000409) under a manual map. See
REM BackstageInjection-Rust/build.rs and protocol/README.md. Requires the
REM x86_64-pc-windows-gnu target and a mingw-w64 gcc for the cc crate.
