clang support the array initialization shorthand syntax
  [ first ... last ] = value
<https://gcc.gnu.org/onlinedocs/gcc-10.2.0/gcc/Designated-Inits.html>,
at least in clang >= 4.

        regex: Use initializer shorthand syntax also with clang.
        * lib/regcomp.c (utf8_sb_map): Use the initializer shorthand syntax also
        with clang.
