        su.1 su.c 
Log Message:
* Notify of impending password or account expiry (check against
  _PASSWORD_WARNDAYS from <pwd.h>). For non-root users, enforce expiry when
  it happens. From Simon Gerraty <sjg%zen.void.oz.au@localhost> in [bin/935].
* Check for group 0 in process's current group membership (as returned by
  getgroups(2)), instead of just looking at the entry for wheel in /etc/group.
  Based on code by Dan Caresone <dan%oink.geek.com.au@localhost> in [bin/792], 
and
  also solves [bin/2466].
* Clean up to pass -Wall
