The draft address space names have been replaced by their final names, which is
__flash now. The draft __pgm is no more supported.

Updated test case:
==================

struct rgb { char r, g, b; };

char read_rgb_ok (const __flash struct rgb *s)
{
    return s->r + s->g  + s->b;
}

char read_rgb_bug (const __flash struct rgb *s)
{
    struct rgb t = *s;

    return t.r + t.g  + t.b;
}
