 Replying to [comment:13 glynn]:

 How about this:

 {{{
 CFLAGS="$CPPFLAGS $CFLAGS" CXXFLAGS="$CPPFLAGS $CXXFLAGS" CPPFLAGS=`echo
 $CPPFLAGS | sed 's/-D_FORTIFY_SOURCE=.//g'` ./configure
 }}}

 This way I'm passing all CPPFLAGS as declared in /etc/makepkg.conf to
 CXXFLAGS and CFLAGS for make, I don't give up on CPPFLAGS entirely in case
 it contained anything that configure could need, but I drop
 D_FORTIFY_SOURCE from CPPFLAGS for configure, to avoid the
 "_FORTIFY_SOURCE requires compiling with optimization" issue. Seems least
 intrusive and foolproof?
