        * c-fold.c (c_fully_fold_internal): Also emit shift count
        warnings for vector types.
        * c-typeck.c (build_binary_op): Likewise.

Hello,

I just wanted to advertise the function element_precision, whose goal is 
to unify handling of vectors and scalars. It is "overloaded" to apply 
TREE_TYPE the right number of times before TYPE_PRECISION. Since you are 
giving a different warning message for scalars and vectors, it probably 
wouldn't help you here though. (OTOH, if you decided that the same message 
was good enough for both...)
