Deprecated attributes applied via typedefs, like INT2, are weaker in other ways
too: for example my fix for c++/58305 isn't enough for those.

seems to work.

Another difference between C and C++:

[...@gnu-6 tmp]$ cat bad.i
typedef int INT2 __attribute__((deprecated));
int f5(INT2 x);
int f6(INT2 x) __attribute__((deprecated));
[...@gnu-6 tmp]$ gcc -S bad.i
bad.i:2: warning: ‘INT2’ is deprecated
bad.i:3: warning: ‘INT2’ is deprecated
[...@gnu-6 tmp]$ g++ -S bad.i
bad.i:2: warning: ‘INT2’ is deprecated (declared at bad.i:1)
[...@gnu-6 tmp]$
