 It would be nice if this could be automated. Or maybe there is a newer
 AC_PROG_LIBTOOL macro that does the right thing. But for now this is fine
 to commit. I tested it with clang++

 This part I don't think needs to be in the changelog.

 Also the error with that may need a different bug ticket. I hit it but
 didn't explore. I then did "make CXXFLAGS=-g" and make completed.

 why (yet), maybe it's too complicated?  In any case if we want to solve it
 this should go to a separate ticket.


 Yes, different ticket.
