According to the documentation:
The deprecated attribute results in a warning if the type is used anywhere
in the source file.
The following test case shows that when applied to an enum definition the
attribute has no such effect (this is in contrast to applying the attribute
to a class definition where it does have the expected effect):
$ cat -n u.cpp && g++ -dumpversion && g++ -W -Wall -Werror -c u.cpp; echo $?
1 enum __attribute__ ((deprecated)) E { e };
2 struct S { enum __attribute__ ((deprecated)) F { f = e }; };
3
4 int main () {
5 E x;
6 x = e;
7
8 S::F y;
9 y = S::f;
10
11 return x + y;
12 }
