Quoting my sibling comment:
Except it was written in a completely different language (Rust), which likely would have necessitated a completely different architecture, and nobody has established any relationship either algorithmically or on any other level between that compiler and TCC. Additionally, and Anthropic's compiler supports x86_64 (partially), ARM, and RISC-V, whereas TCC supports x86, x86_64, and ARM. Additionally, TCC is only known to be able to boot a modified version of the Linux 2.4 kernel[1] instead of an unmodified version of Linux 6.9.
Additionally, it is extremely unlikely for a model to be able to regurgitate this many tokens of something, especially translated into another language, especially without being prompted with the starting set of tokens in order to specifically direct it to do that regurgitation.
So, whatever you want to say about the general idea that all model output is plagiarism of patterns it's already seen or something. It seems pretty clear to me that this does not fit the hyperbolic description put forward in the parent comments.
