Are you saying this will allow ITKv4 to be built with current gcc?  At 
present, ITK is about to be removed from testing tomorrow because it won't 
build.

Yep, I've already uploaded ITK 5 to Debian.

Yes.  This is what I've communicated already 2-3 times on the list -- going 
back a year -- and in Ghislain's ITP.

If we can get ITK4 to build with current compilers, my suggestion would be to 
make a v4 branch in the current repository.  On the other hand, it's kind of 
11th hour here.  I'm much more focused on replacing v4 with v5 -- which, to be 
fair is already more than two years old.  ITK v4 is no longer supported 
upstream.

Yes, I've always used debian-med for communications.  Additional hands are 
always welcomed.
