           Summary: [Qt] Remove Qt v4.6 check from the prefetchDNS
                    implementation
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: All
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: WebKit Qt
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: laszlo.1.gombos at nokia.com


Functionality behind r47425 (http://trac.webkit.org/changeset/47425) is guarded
with Qt v4.6 build check. Typically we do not use a build time Qt version check
for newly introduced QtWebKit functionality. The usage of Qt version check is
should be restricted to guard QtWebKit functionality that depends on a Qt
functionality that is not available in all Qt versions. 

In this particular case the functionality introduced by r47425 builds and
functions just fine using Qt v4.5. In addition removing the build flag also
gets rid of a build warning (from moc).
