rust non-free-compatible trademark

> Normal use of a word isn't something that Trademarks prevent.

In general, no, but what it prevents is using the word in a way that
would produce confusion with an "official" use of that mark.  If the
word that constitutes the mark is too general, then the trademark
shouldn't have been granted.  But let's assume that somebody has
trademarked a common adjective, which we'll call "adjective", when
applied to noun "noun".

If I write "I have an adjective noun", that's supposed to refer to the
trademarked it.  If it instead refers to some other item (e.g., in our
case a compiler with patches), that's a trademark violatio.
