Explicit braces were added to fix the "suggest explicit braces to avoid ambiguous ‘else’" warning since the current solution (switch (0) case 0: default:) doesn't work since gcc 7 (see https://github.com/google/googletest/issues/1119) gcc 13 generates about 5000 of these warnings when building libc without this patch.
