good idea to make <ctrl>+<enter> a shortcut to send the message.)

I have this in <elf.h> in ppc64-linux:

typedef struct
{
  uint64_t a_type;              /* Entry type */
  union
    {
      uint64_t a_val;           /* Integer value */
      /* We use to have pointer elements added here.  We cannot do that,
         though, since it does not work when using 32-bit definitions
         on 64-bit platforms and vice versa.  */
    } a_un;
} Elf64_auxv_t;

So default_auxv_parse seems right to me.
