Why are you using a default profile with a hardened USE-flag/kernel? Take a look at http://www.gentoo.org/proj/en/hardened/selinux/selinux-amd64-handbook.xml?part=0&chap=0 Also, http://www.gentoo.org/proj/en/hardened/hardenedxorg.xml I don't see these problems on my non-hardened/x86.
I'm using a default like that because I haven't tuned it yet. I just got this to compile by applying the 3 changes to Xorg while the emerge was running. So whether it happened on your system or not, the problems exist in the c files.
I'm not saying the compile didn't fail (it didn't), but in the case of one or two of those files the suggested problems don't exist. The stdio include is actually in the .c file that you say it's missing from. As far as I know you can't mixed hardened stuff with a non-hardened profile, and this could potentially cause wacky stuff to happen.
