 Is this still a problem?

Not anymore, the 4.0 vs 4.1 compat testsuite is now clean both in 32-bit and
64-bit mode.

I certainly can't reproduce this on sparc*-linux:
struct B1_m_outer_p_inner {
  char c;
  double d;
} __attribute__ ((aligned)) __attribute__ ((packed)) s;
extern void abort (void);
int main ()
{
  char *p, *q;
  if (sizeof (struct B1_m_outer_p_inner) != 16 || __alignof__ (struct
B1_m_outer_p_inner) != 8
  || sizeof (s) != 16 || __alignof__ (s) != 8
  || __alignof__ (s.c) != 1
  || __alignof__ (s.d) != 1)
abort ();
  p = s.c;
  q = (char *) s.d;
  if (q - p != 1)
abort ();
  return 0;
}

succeeds with both GCC 3.4.x and current trunk.
