config.log
Hello.
Starting from r223691, I have following error in stage1:
g++ -c -g -DIN_GCC -fno-exceptions -fno-rtti -fasynchronous-unwind-tables
-W -Wall -Wno-narrowing -Wwrite-strings -Wcast-qual -Wno-format
-Wmissing-format-attribute -Woverloaded-virtual -pedantic -Wno-long-long
-Wno-variadic-macros -Wno-overlength-strings -fno-common -DHAVE_CONFIG_H
-DGENERATOR_FILE -I. -Ibuild -I../../gcc -I../../gcc/build
-I../../gcc/../include -I../../gcc/../libcpp/include \
-o build/genmddeps.o ../../gcc/genmddeps.c
cc1plus: error: unrecognized command line option "-Wno-narrowing"
I see very suspicious lines in config.log file which I attached:

configure:6406: g++ -c -g conftest.cpp >&5
