It works OK for the other Free languages like perl, python, ruby, and
indeed the gcc implementation of C/C++.

No single distribution ships a weirdly broken implementation of any of
these languages[1] since to do so would make the distribution less
useful. There's no need for the licence to enforce basic sanity, the
distros and their users do that themselves. If someone comes up with an
extension that actually seems useful then everyone can adopt it; either
way everyone stays compatible because everyone wants compatibility.

[1] OK, so there was the gcc 2.96 aberation. Other than that.....
