I checked the debhelper change, and it does set CXXFLAGS.  Looking at e.g.
https://buildd.debian.org/status/fetch.php?pkg=schroot&arch=powerpc&ver=1.6.8-1&stamp=1388838030:

  -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security

are being added.  So at least some options are being set automatically.
Is _FORTIFY_SOURCE passed using a different mechanism or a different variable?
Or do I need to take some additional measure to explicitly enable it?
