typeof_unqual behaves differently in gcc and clang
  • C23 6.7.3.6 contains this (informative) example demonstating the use of `typeof_unqual`:
  • ```c
  • const char* const animals[] = {
  • "aardvark",
  • "bluejay",
  • "catte",
  • };
  • typeof_unqual(animals) animals2_array[3];
  • ```
  • And this is supposedly equivalent to `const char* animals2_array[3];` according to the example. That is also the result I get from clang 19.1.
  • But in gcc 14.2 I get the type `const char* const [3]`.
  • Full example: https://godbolt.org/z/Gf9M43nrM
  • What is correct? Is the standard unclear? The parts about `typeof_unqual` in 6.7.3.6 do not mention arrays at all.
