1) bool IsVisible() const { return ((m_flags &
a2dREFTEMPLATE_VISIBLE) == a2dREFTEMPLATE_VISIBLE); }
produces

'==' in function a2dDocumentTemplate::IsVisible() const

2) bool IsVisible() const { return (((a2dTemplateFlag)(m_flags &
a2dREFTEMPLATE_VISIBLE) == (a2dTemplateFlag) a2dREFTEMPLATE_VISIBLE)); }
produces

It looks as though option 2 effectively operates correctly, so I would
suggest going with option 2, but that still leaves the error from
wxWidgets wxDocTemplate::IsVisible() ??
