/* BB_AUDIT SUSv3 compliant */
/* http://www.opengroup.org/onlinepubs/007904975/utilities/logname.html */
/* Mar 16, 2003 Manuel Novoa III (mjn3@codepoet.org)
*
* SUSv3 specifies the string used is that returned from getlogin().
* The previous implementation used getpwuid() for geteuid(), which
* is _not_ the same. Erik apparently made this change almost 3 years
* ago to avoid failing when no utmp was available. However, the
* correct course of action wrt SUSv3 for a failing getlogin() is
* a dianostic message and an error return.
