            Bug ID: 194290
           Summary: [WPE] WindowViewBackend does not build because of
                    wl_array_for_each macro
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW

WindowViewBackend does not build with clang, because the wl_array_for_each() macro is used with a pointer to void, which does not allow to do arithmetic:

Tools/wpe/backends/WindowViewBackend.cpp:445:106: error: arithmetic on a pointer to void
        for (p = (states)->data; (const char *) p < ((const char *) (states)->data + (states)->size); (p)++)
                                                                                                      ~~~^
