My app uses qextserialport, so I rebuilt that with the linker flag. Also I rebuilt my app with the linker flag. Unfortunately, it still complains about the libgcc_s_dw2-1.dll.
When I run depends, the missing dll shows up inside the tree for QtGUI.dll and QtCore4.dll. Does this mean I have to reconfigure Qt with the new linker flag?
