In configure script, it searches in order: -O3 availability in compiler - and appends when available -O2 availability -||-
Please post your `emerge --info' and attach the config.log.
Hm, yes, confirmed: it does seem to "prefer" -O3, while leaving other compiler flags alone.

Thank you for report, Macie. Upstream still respect other CFLAGS they know nothing about: x86_64-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I.. -I. -DNDEBUG -Wall -O3 -Wno-non-virtual-dtor -pthread -DTHREADMODEL=POSIXTHREADS -pipe -march=athlon64 -mtune=athlon64 -msse3 -fomit-frame-pointer -ftracer -c GString.cpp -fPIC -DPIC -o .libs/GString.o -Wall -O3 -Wno-non-virtual-dtor - upstream suggested. -pipe -march=athlon64 -mtune=athlon64 -msse3 -fomit-frame-pointer -ftracer - CFLAGS from /etc/make.conf. So they do respect our CFLAGS but not all. I don't think I'm going to fix -O2/-O3 issue reported here. But I see that they require us to use --enable-debug switch to be able to pass debugging CFLAGS (-g*) and I'll fix this.
Hello. I like my CFLAGS to be absolutely respected by package(s). In my opinion you can ignore upstream/author`s suggestion because we are Gentoo doing things ourselves. If it cannot be compiled or it will be not running with my (hopefully) safe CFLAGS (-O2 -pipe -g -ggdb) and NOSTRIP feature I`ll be one of the reporters to the upstream/authors. Thank you.
Dropping all CFLAGS parsing code was easier... Fixed in 3.5.22-r1.
