[Bug c/14142] New: attribute(aligned())) has no effect with typedef's

["gp at qnx dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Consider:
#include <stddef.h>
typedef unsigned long long _Uint64t __attribute__((__aligned__(8)));

typedef struct
{
    unsigned int        a;
    _Uint64t            b __attribute__((__aligned__(8)));
} my_aligned_struct;

typedef struct
{
    unsigned int        a;
    _Uint64t            b;
} my_struct;

int main(int argc, char ** argv)
{
    printf("offset of b : %d\n", offsetof(my_aligned_struct,b));
    printf("offset of b : %d\n", offsetof(my_struct,b));
    return 0;
}

The offset of 'b' should be 8 in both cases, but it is 4 when the attribute 
aligned is only applied to the typedef (using gcc-3.3.3 prerelease Feb 10 2004).
