‘OUTPUT_DRAWMODE_CONTRAST’ defined but not used

In may build I see this warning a lot:
In file included from cui/source/tabpages/textattr.cxx:37:0:
include/svx/dlgutil.hxx:37:28: warning: ‘OUTPUT_DRAWMODE_CONTRAST’ defined but not used 
[-Wunused-variable]
 static const DrawModeFlags OUTPUT_DRAWMODE_CONTRAST = DrawModeFlags::SettingsLine | 
DrawModeFlags::SettingsFill | DrawModeFlags::SettingsText | DrawModeFlags::SettingsGradient;

I’m guessing it is caused by the static in the declaration since
OUTPUT_DRAWMODE_CONTRAST seems to be used somewhere.

Hmm, we have two declarations of OUTPUT_DRAWMODE_CONTRAST, the other one
in sd/source/ui/inc/ViewShell.hxx and a macro in
svx/source/dialog/dlgctrl.cxx, so I’m a bit lost…
