Subject: bug#64917: 30.0.50; c-ts-mode throws warnings about missing cpp support
Date: Fri, 28 Jul 2023 11:14:15 +0200

I built master with tree-sitter support, and installed the c-language
grammar using M-x treesit-install-language-grammar. I have
libtree-sitter-c.so in ~/.emacs.d/tree-sitter

I restarted emacs, visited src/xdisp.c, and did M-x c-ts-mode, which
popped up a *Warnings* buffer containing:

⛔ Warning (treesit): Cannot activate tree-sitter, because language grammar for cpp is unavailable (not-found): (libtree-sitter-cpp libtree-sitter-cpp.0 libtree-sitter-cpp.0.0 libtree-sitter-cpp.so libtree-sitter-cpp.so.0 libtree-sitter-cpp.so.0.0) No such file or directory
⛔ Warning (treesit): Cannot activate tree-sitter, because language grammar for cpp is unavailable (not-found): (libtree-sitter-cpp libtree-sitter-cpp.0 libtree-sitter-cpp.0.0 libtree-sitter-cpp.so libtree-sitter-cpp.so.0 libtree-sitter-cpp.so.0.0) No such file or directory

which is less than desirable (althoug `major-mode' is c-ts-mode, so I
guess things worked)
