            Bug ID: 66304
           Summary: Can't bootstrap on x86_64-linux-gnu with gcc 4.3.4
           Product: gcc
           Version: 5.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

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:6330: result: yes
configure:6382: checking for int64_t underlying type
configure:6406: g++ -c -g   conftest.cpp >&5
configure:6406: $? = 0

configure:6502: $? = 0
configure:6511: result: yes
configure:6485: checking whether gcc supports -Wall

configure:6511: result: yes
configure:6485: checking whether gcc supports -Wnarrowing
configure:6502: g++ -c -g   conftest.cpp >&5
configure:6502: $? = 0

Thanks,
Martin

Yeah, sorry, it's really against trunk.
