C++ PATCH: tidy diagnostic about invalid of use of automatic variable

[Gabriel Dos Reis]

Now that we can actually declare a variable as `auto', it becomes
important to be precise in our terminology when diagnosing invalid
uses of variables with automatic storage -- especially if the variable
isn't declared 'auto'.

Applied to trunk.
