No what I am saying if you want accurate warnings for building 4.0.0, you need
4.0.0 but since we don't
build cross compilers with -Werror for a reason.
Basically we added more formating in 4.0.0 which are not supported at all in
3.4.0 so warning about
them in 3.4.0 is useful as you know that you messed up when back porting a
patch to the 3.4.0 when
compiling natively. If you use an earlier version of gcc than 3.4.0, you don't
get this warnings at all.
The only way to fix this would depend on using the formatting warnings only for
that certain version of
gcc (I would assume that the formatting warnings are useful even if we don't
support them in 3.4.0
because you can reconize what version you using to cross compile with).
And yes you should be really using the same version to cross compile with as
then it does not get
confussing when something gets miscompiled (which has been known to happen in
the past).
