I've just built rust from the latest git and it still seems true (at least with the default compiler flags). The "hello world" from the tutorial compiles to a 1MB executable (dynamically linked with the C library but statically linked with the rust library). The equivalent C program creates a 6.5KB binary with gcc.

It goes a lot smaller with `--codegen prefer-dynamic`, also around 6K for me.

But AFAIK there is a subset of Rust which doesn't require the runtime.

  The language itself doesn't need the runtime: it's entirely implemented in libraries, and the libraries are slowly being rearranged to offer as much as possible to clients who wish to avoid the runtime (e.g. "libcore").
