I should note that this patch does not break compilation with wxWidgets 2.8, it is backwards compatible.
There is one iffy bit however, but I believe that it is ok. It is in the line below, you can search for it in the patch.
src/utils/wxfbipc.cpp: return ( wxChar* )( m_data.wx_str() ); // FIXME-JRL

Closed the ticket because it is quite old. Please create a new ticket if you still have build issues.
