I suspect this is no longer a problem with current releases.  They all build
with -O2 and -Werror.

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.

The expmed.c code is broken, not sure about the crtstuff one.
