+------------------------------------------------------------------------
+_PATH_UTMP and UTMP_FILE and UTMP_FILENAME
+	/etc/utmp > /var/adm/utmp > /var/run/utmp.
+Traditionally we have /etc/utmp.
+In <paths.h> we have /etc/utmp, but since 4.6.0 /var/adm/utmp
+and since 5.0.9 (and in glibc2) /var/run/utmp.
+In login/pathnames.h we have /etc/utmp, but since 4.6.6 /var/adm/utmp.
+In <utmp.h> UTMP_FILE is defined as /etc/utmp, but in 4.6.* as _PATH_UTMP.
+
+_PATH_WTMP and WTMP_FILE and WTMP_FILENAME
+	/etc/wtmp > /usr/adm/wtmp > /var/adm/wtmp > /var/log/wtmp.
+Traditionally we have /etc/wtmp.
+In <paths.h> we have /usr/adm/wtmp, but since 4.5.13 /var/adm/wtmp,
+and since 5.0.9 (and in glibc2) /var/log/wtmp.
+In login/pathnames.h. we have /etc/wtmp, but since 4.6.6 /var/adm/wtmp.
+In <utmp.h> WTMP_FILE is defined as /usr/adm/wtmp, but in 4.5.* as
+/var/adm/wtmp, and in 4.6.* as _PATH_WTMP.
+
+_PATH_DEFPATH
+Long ago this was ".:/bin:/usr/bin".
+In <paths.h> libc 4.4.1-4.4.4 have "/usr/bin:/bin"
+and libc 4.5.21-5.4.23 have "/usr/local/bin:/usr/bin:/bin:."
+and libc 5.4.38-5.4.46 have "/usr/local/bin:/usr/bin:/bin".
+In login/pathnames.h libc4 and libc5 have "/usr/local/bin:/bin:/usr/bin:."
+
+_PATH_DEFPATH_ROOT
+Long ago this was identical to _PATH_DEFPATH.
+In <paths.h> no definition is present before libc 4.5.13.
+Libc 4.5.13 has "/bin:/usr/bin:/etc"
+Libc 4.5.14-5.4.46 have "/sbin:/bin:/usr/sbin:/usr/bin"
+In login/pathnames.h libc4 and libc5 have "/bin:/usr/bin:/etc"
+
+_PATH_LASTLOG
+	/etc/lastlog > /usr/adm/lastlog > /var/adm/lastlog > /var/log/lastlog.
+Traditionally we have /etc/lastlog.
+In <bsd/utmp.h> libc 4.4.1-4.5.12 have /usr/adm/lastlog, 4.5.13 and
+later have /var/adm/lastlog.
+In paths.h all libc5 and glibc2 versions have /var/log/lastlog.
+In login/pathnames.h all libc4 and libc5 versions have /usr/adm/lastlog.
+
+_PATH_MAILDIR
+	/usr/spool/mail > /var/spool/mail > /var/mail.
+Traditionally we have /usr/spool/mail.
+In <paths.h> we have /usr/spool/mail, but since libc 4.5.13 /var/spool/mail.
+In login/pathnames.h all libc4 versions have /var/spool/mail.
+Libc5 and glibc 2.0-2.1 have /var/spool/mail, but glibc 2.1.1 has /var/mail.
