Attribute unused is used in cases where in C++ you can write
void f(int /*p*/) {
...; /* doesn't use p, but did in the past; we don't want to change
the prototype, though */
}
which you can't do in C.
Deprecated was deemed useful enough to be included into the Java standard.
Attribute weak changes the semantics of a function w.r.t. the linker.
That being said, it might well be that some of the attributes are useless.
That should not tempt us into creating more uselessness, though.
IMHO, your proposal is absolutely useless, since
- one can get the same effect with a minimal change
- it would have a ridiculously far-reaching impact since it would
essentially introduce overloading assignment operators in C.
