            Bug ID: 211044
           Summary: [WTF] Workaround gcc bug for unsigned bitfield related
                    usual arithmetic conversions
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
          Assignee: webkit-unassigned at lists.webkit.org

(unsigned + signed) should return unsigned int type as a common type defined by usual arithmetic conversions.

But gcc 9.3.0 returns signed int type for this case.

I filed a bug for this issue on gcc bugzilla,
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=94767.

To workaround this, I originally submitted the patch, http://svn.webkit.org/repository/webkit/trunk@260715,
but according to Darin's comment, use unsigned integer suffix instead of static_cast<unsigned>.
