attr_get warning when on ubuntu 13.04

[Gaute Hope]

Greetings,

I'm getting some compiler warnings when using attr_get and wattr_get on
Ubuntu 13.04 which I don't get elsewhere:

  warning: the compariosn will always evaluate as 'true' for the address
  of 'attrs' will never be NULL [-Waddress]
  warning: the comparison will always evaluate as 'true' for the address
  of 'pair' will never be NULL [-Waddress]

  (gcc 4.7.3)

this is with code that goes like this:

  attr_t attrs = 0;
  short  pair  = 0;
  int ret = attr_get(&attrs, &pair, 0);

I am guessing the macros have been tweaked between the ncurses versions,
can you confirm this?

(in which case I will just ignore the warning and wait for Ubuntu to tag
along..)

Cheers, Gaute
