warning: undefined preprocessor identifier '_FORTIFY_SOURCE'

Can you paste that line?

Over here it looks like there's a construct to make sure that it's set
before testing it..

if defined _fort && _fort > 0
    stuff

I wonder if you have some glibc that just does a

if _fort > 0

and doesn't have the defined guard?

I'm just guessing, though.
