--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
Reduced:
$ cat x.h
#pragma GCC system_header
enum E { _A, _B, _C };
$ cat x.C
#include "x.h"
void
g ()
{
E e = _A;
switch (e)
{
case _A:
case _B:
break;
}
}
$ ./cc1plus -quiet x.C -Wswitch
x.C: In function ‘void g()’:
x.C:7:10: warning: enumeration value ‘_C’ not handled in switch [-Wswitch]
7 | switch (e)
| ^
Suppressing the warning when the enumerator comes from a system header should
be fairly easy using in_system_header_at. But for the "use reserved names"
requirement -- should we just check whether the name of an enumerator starts
with an '_'?
