  3.                  from c:/Qt/4.4.1/include/QtGui/qpushbutton.h:1,
  4.                  from c:/Qt/4.4.1/include/QtGui/QPushButton:1,
  5.                  from ./ui_form3.h:18,
  6.                  from form3.h:3,
  7.                  from form1.cpp:2:
  8. c:/Qt/4.4.1/include/QtGui/../../src/gui/widgets/qabstractbutton.h:55: error: `QtValidLicenseForGuiModule' does not name a type
