/*
* HP-UX does not have issetugid().
* This experimental implementation uses pstat_getproc() and get*id().
* First, try pstat_getproc() and check PS_CHANGEDPRIV bit of pst_flag.
* In case unsuccessful calling pstat_getproc(), using get*id().
*
* Use pstat_getproc() and check PS_CHANGEDPRIV bit of pst_flag. If this call
* cannot be used, assume we must be running in a privileged environment.
