--- Comment #2 from Simon Richter <Simon.Richter at hogyros dot de> ---
In 4.8, this causes build failures for me:

$ g++ -g -Wall -W -Werror -Wno-unused -I. -o stage1/tree_bison_lex.o -c
tree_bison_lex.cpp
tree_bison_lex.cpp:1744:13: error: unused parameter 'yyscanner'
[-Werror=unused-parameter]

As can be guessed from the name, this is a file that is generated from flex,
which is why I've added -Wno-unused for this file specifically.

4.7 did not warn.
