Ah yes, you're right.

I definitely see it on x86 too using the following testcase:
2292:[EMAIL PROTECTED]: ~/tmp/src] gcc-4.1 -c t.c
t.c: In function ‘f’:
t.c:9: error: assignment of read-only variable ‘__v’
zsh: exit 1 gcc-4.1 -c t.c
2293:[EMAIL PROTECTED]: ~/tmp/src] cat t.c
struct rx_length_info
{
unsigned short tag;
};
void f(void)
{
const struct rx_length_info *length_info;
__typeof__ (*(&length_info->tag)) __v;
__v = *(&length_info->tag);
}
2294:[EMAIL PROTECTED]: ~/tmp/src] uname -a
