  27 What is the history of these six, and related defines?
  28 ------------------------------------------------------------------------
  29 _PATH_UTMP and UTMP_FILE and UTMP_FILENAME:
  30         /etc/utmp > /var/adm/utmp > /var/run/utmp.
  31 Traditionally we have /etc/utmp.
  32 In <paths.h> we have /etc/utmp, but since 4.6.0 /var/adm/utmp
  33 and since 5.0.9 (and in glibc2) /var/run/utmp.
  34 In login/pathnames.h we have /etc/utmp, but since 4.6.6 /var/adm/utmp.
  35 In <utmp.h> UTMP_FILE is defined as /etc/utmp, but in 4.6.* as _PATH_UTMP.
  36
  37 _PATH_WTMP and WTMP_FILE and WTMP_FILENAME:
  38         /etc/wtmp > /usr/adm/wtmp > /var/adm/wtmp > /var/log/wtmp.
  39 Traditionally we have /etc/wtmp.
  40 In <paths.h> we have /usr/adm/wtmp, but since 4.5.13 /var/adm/wtmp,
  41 and since 5.0.9 (and in glibc2) /var/log/wtmp.
  42 In login/pathnames.h. we have /etc/wtmp, but since 4.6.6 /var/adm/wtmp.
  43 In <utmp.h> WTMP_FILE is defined as /usr/adm/wtmp, but in 4.5.* as
  44 /var/adm/wtmp, and in 4.6.* as _PATH_WTMP.
  45
  46 _PATH_DEFPATH)
  47 Long ago this was ".:/bin:/usr/bin".
  48 In <paths.h> libc 4.4.1-4.4.4 have "/usr/bin:/bin"
  49 and libc 4.5.21-5.4.23 have "/usr/local/bin:/usr/bin:/bin:."
  50 and libc 5.4.38-5.4.46 have "/usr/local/bin:/usr/bin:/bin".
  51 In login/pathnames.h libc4 and libc5 have "/usr/local/bin:/bin:/usr/bin:."
  52
  53 _PATH_DEFPATH_ROOT)
  54 Long ago this was identical to _PATH_DEFPATH.
  55 In <paths.h> no definition is present before libc 4.5.13.
  56 Libc 4.5.13 has "/bin:/usr/bin:/etc"
  57 Libc 4.5.14-5.4.46 have "/sbin:/bin:/usr/sbin:/usr/bin"
  58 In login/pathnames.h libc4 and libc5 have "/bin:/usr/bin:/etc"
  59
  60 _PATH_LASTLOG)
  61         /etc/lastlog > /usr/adm/lastlog > /var/adm/lastlog > /var/log/lastlog.
  62 Traditionally we have /etc/lastlog.
  63 In <bsd/utmp.h> libc 4.4.1-4.5.12 have /usr/adm/lastlog, 4.5.13 and
  64 later have /var/adm/lastlog.
  65 In paths.h all libc5 and glibc2 versions have /var/log/lastlog.
  66 In login/pathnames.h all libc4 and libc5 versions have /usr/adm/lastlog.
  67
  68 _PATH_MAILDIR)
  69         /usr/spool/mail > /var/spool/mail > /var/mail.
  70 Traditionally we have /usr/spool/mail.
  71 In <paths.h> we have /usr/spool/mail, but since libc 4.5.13 /var/spool/mail.
  72 In login/pathnames.h all libc4 versions have /var/spool/mail.
  73 Libc5 and glibc 2.0-2.1 have /var/spool/mail, but glibc 2.1.1 has /var/mail.
