--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> --- With r263561 brace-enclosed initializers for constant character arrays are handled by transforming them into STRING_CSTs. It should be possible to also handle wide character types (wchar_t, char16_t, char32_t). Handling arrays of arbitrary integers will probably take a different approach.
