http://trac.webkit.org/changeset/110272 broke the Qt-Win build with the following error message: /usr/lib/gcc/i486-mingw32/4.5.2/../../../../i486-mingw32/bin/ld: cannot find -lQtWebKitd4 make[5]: *** [../../../../imports/QtWebKit/qmlwebkitplugind.dll] Error 1 It seems after this patch QtWebKitd4.dll became QtWebKitd.dll somehow.
Should be fixed by r110436
