gcc 4.1.2 compiler issues an error that 'a.x' is not a constant while I expect
'a.x' is a constant.
$ cat test.c
#include <stdio.h>
struct s{
int i;
enum {x};
}a;
int main(void)
{
switch(1){
case a.x: ;
}
return 0;
}
$ g++ test.c
test.c: In function 'int main()':
test.c:11: error: 'a' cannot appear in a constant-expression
test.c:11: error: `.' cannot appear in a constant-expression
$ g++ --version
