The problem is the -fno-stack-protector-all flag as apparently this isn't supported after GCC-4.1
Thanks for reporting back the answer, guess we can close this bug then.
Sorry, I misinterpreted your second comment at first. Now I see that you didn't have -fno-stack-protector-all in your CFLAGS, so nagios-plugins must have enabled it...

Perhaps its a feature of Gentoo and I need to emerge -e system && emerge -e world again! :-(

Probably it's because of the hardened toolchain you're using. I fail to reproduce this on some hardened boxes, though. Can you please re-test with 1.4.14-r1 and re-open this bug if this issue still exists?
