--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
On e.g.
struct A {};
struct __attribute__((deprecated)) B {};
typedef struct A C __attribute__((deprecated));
void f1 (struct A *);
void f2 (struct B *);
void f3 (C *);
void f4 (const struct A *);
void f5 (const struct B *);
void f6 (const C *);
the r12-7287 change when compiled by C++ differs just with one extra
+aaa.c:2:36: note: declared here
+    2 | struct __attribute__((deprecated)) B {};
+      |                                    ^
which wasn't there before, but in C changes:
-aaa.c:6:1: warning: ‘C’ is deprecated [-Wdeprecated-declarations]
+aaa.c:6:1: warning: ‘A’ is deprecated [-Wdeprecated-declarations]
and
-aaa.c:9:1: warning: ‘C’ is deprecated [-Wdeprecated-declarations]
+aaa.c:9:1: warning: ‘A’ is deprecated [-Wdeprecated-declarations]
