latte-int doesn't compile with gcc-11

[kiwifb]

This is due to new behavior in c++17 which is now the default for g++

/bin/sh ../../libtool  --tag=CXX   --mode=compile x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I../../code  -I../../code -DINSTALLDIR=\"/usr/bin\"      -D__STDC_LIMIT_MACROS -D_4ti2_GMP_   -march=native -O2 -pipe -c -o PolyTree.lo PolyTree.cpp
