Bug#871811: FTBFS with CGAL 4.11

Followup-For: Bug #871811

Hi,

I would like to update CGAL to 4.11 (currently in experimental), but your
package FTBFS. The access to CGAL::IO::Mode has been changed again. Attached is
a patch that fixes the problem for <= 4.9, 4.10 and >= 4.11. With that patch,
it builds again, but I don't know how to test it.
