In my gcc/Makefile, I see:
CFLAGS = -g
CXXFLAGS = -g -O2
This makes builds in the gcc directory default to -O2, before they were -O0. -O0 aides in debugging for people that develop the compiler. Do you see this?
# Remove the -O2: for historical reasons, unless bootstrapping we prefer
# optimizations to be activated explicitly by the toplevel.
case "$CC" in
*) CFLAGS=`echo $CFLAGS | sed "s/-O[[s0-9]]* *//" ` ;;
in configure.ac does this. I think if CXXFLAGS is also so done, we'd gain parity.
