Here is a workaround -- use a newer compiler like clang-11

It's a fairly common problem. Using legacysupport is a cheaper workaround. See #66055 for an example.

[jmroot (Joshua Root)]

It's already using legacysupport, and requiring a C11 capable compiler. What it's not doing is passing -std=c11 to the compiler.

[ryandesign (Ryan Carsten Schmidt)]

Because tree-sitter-cpp is using the tree_sitter portgroup which completely overrides the configure, build, and destroot phases with its own commands. Why does it do that? ​tree-sitter-cpp ships with a Makefile that does specify -std=c11. Why isn't the port using that?
