[Chicken-users] Replacement for posix.scm directory function

[tonyg]

Hi...

I just realised that on HP/UX, the C library etc. will often return
pointers that look like "0x7f......". This means that using
C_fix/C_unfix to wrap these pointers will not work.

I chanced upon this when using posix.scm's (directory <dirname>). I've
attached a reimplementation which uses address->pointer instead of
C_fix/C_unfix... could people please review it, and if it's okay, I'll
commit it tomorrow?

Thanks.

(Of course, there's still more work to go checking each use of C_fix
to see if it's encoding a pointer which might have the high 2 bits set
to 01... darn!)

Cheers,
  Tony
