crustc: entirety of `rustc`, translated to C

A developer has created "crustc," a fully functional Rust compiler translated into 46 million lines of C code that can be compiled with GCC and Make. The project demonstrates "cilly," a new Rust-to-C compiler toolchain developed over three years that adapts generated C code to work with various C compilers and platforms, with the goal of enabling Rust support on obscure hardware and systems that lack LLVM/GCC support but have C compilers available.
