            Bug ID: 241524
           Summary: Unified build: error: reference to 'FontInfo' is
                    ambiguous
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: yurys at chromium.org
                CC: kkinnunen at apple.com

We are getting the following error in our build. The error is likely caused by 'using namespace WebKit;' in one of the .cpp files compiled as part of the same UnifiedSource82.cpp.
