--- Comment #1 from Martin Sebor <msebor at gcc dot gnu.org> ---
The new -Wattributes warning is the (deliberate) result of r255469. The only
meaningful effect a call can have to a function that's declared with the const
attribute is return a value. Calls to such functions that ignore the returned
value are eliminated (and diagnosed with -Wunused-value). Likewise, calls to
const functions that return void are eliminated (though without a warning,
which seems like an omission). As a result, it makes little sense to declare a
function to be both const and return void, and -Wsuggest-attribute=const should
not be issued for const functions.
