feature: Support for C23's typeof()

[richarno]

Did you check the tree-sitter docs?

• I have read all the tree-sitter docs if it relates to using the parser

Is your feature request related to a problem? Please describe.

Hello,
I tried to implement support for the "typeof" C23 feature.
The following snippet of code is valid:

typeof(int) a;

However it raises an error when parsed with the tree-sitter-c grammar.

Describe the solution you'd like

I tried to add the following line in the grammar.js file, in type_specifier:

  $.typeof_specifier,

And later in that same file I added:

    typeof_specifier: $ => seq(
      choice('__typeof', '__typeof__'),
      '(',
      choice($.expression, $.type_descriptor),
      ')',
    ),

Unfortunately this is not enough: The grammar still parses the line above as a function declaration, and obviously it fails and produces an ERROR node.
How can I force the parsing of a typeof(x) as a type_specifier instead of a function declaration?

Thanks.
