{{{
CFLAGS="$CPPFLAGS $CFLAGS" CXXFLAGS="$CPPFLAGS $CXXFLAGS" CPPFLAGS=`echo
$CPPFLAGS | sed 's/-D_FORTIFY_SOURCE=.//g'` ./configure
}}}
It would be better if any _FORTIFY_SOURCE definition could be extracted
and moved into CFLAGS/CXXFLAGS, e.g.
{{{
FORTIFY_FLAGS=`echo "$CPPFLAGS" | sed
'/^.*\(-D_FORTIFY_SOURCE=.\).*$/s//\1/'`
CPPFLAGS=`echo "$CPPFLAGS" | sed 's/-D_FORTIFY_SOURCE=.//g'`
CFLAGS="$FORTIFY_FLAGS $CFLAGS"
CXXFLAGS="$FORTIFY_FLAGS $CXXFLAGS"
}}}
This avoids any potential problems with duplicating the other elements of
$CPPFLAGS.
