Yes: if you use a stable Rust compiler, it won't let you use nightly-only features.

If you want to limit yourself to the features of a specific older Rust compiler, install that Rust compiler and compile with it; we ensure that rustup can install older versions of Rust. (Our standard recommendation for enforcing an MSRV of Rust 1.xy is to build against Rust 1.xy in CI; anything other than that would just be a proxy for what you're actually trying to do.)

And, practically speaking, you need to do the same for C code. Continuing to use -std=c99 is only a very marginal help with ensuring that your codebase is limited to features supported by GCC 4.0, and will still compile with that old compiler.

You really just need to test your build with the versions you want to support.
