I get similar QA notices when compiling gcc-4.6.3 in gentoo. Gentoo package
notes instructed to report this here instead of filing a gentoo bug. I've got
these flags set in /etc/make.conf:

CFLAGS="-fomit-frame-pointer -march=native -O2 -pipe"

Is this something I need to address somehow?

Added QA Notices and gentoo package system emerge --info attachments.
