Following fails to compile: struct S { int x; }; struct S s = {}; // Error: expression expected, not `}` Before C23, this was a common C extension to 0-initialize all fields (accepted by GCC, clang, and maybe MSVC (not sure on that one)). C23 has also added it to standard C.

It was indeed added to C23, see 6.7.10.

Import C is specified as C11 complient, not C23 (https://dlang.org/spec/importc.html#dialect)

But it works on other C99 compilers despite that it's not standardized until C23, so there is a lot of code out there, depending on this.
