It's K&R C, which is used very rarely these days, and it sounds like the
next version of GCC will reject it, since C2x makes it invalid.

So I see no catastrophe that c-ts-mode doesn't support this.  You can always
opt not to use c-ts-mode if you need this style supported.  Of course, if
tree-sitter's parser is updated to add such support, we'll all be happier.
