Before using this kind of high level tool, it's important to know if they are making what we are waiting. To be sure, begin with a simple Makefile is the best practice.

I won't install nightly on my system, I don't want to break it and discover strange error message at the next firfox update.

I have rebuild my binutils, all the needed format are suported.
I will read this doc https://doc.rust-lang.org/rust-by-example/hello.html and this one https://doc.rust-lang.org/nomicon/ffi.html to know what is possible.

Your idea is to call C from Rust in DOS and using DJGPP libc, that's right?
