[Bug c++/21166] New: g++ gives error on reference to packed structure elements

["raj dot khem at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

In the code below, the g++ is being overly picky about taking a reference to a 
packed char.  Chars can have any alignment so the error is incorrect.  note 
that the same code using pointers doesn't produce a similar error:
=====

struct s1 {
	char	c1;
} __attribute__((packed));

char&
f(struct s1 *s)
{
	return s->c1;
}

char *
g(struct s1 *s)
{
	return &s->c1;
}
