dnl	History:
dnl
dnl	Modified by cmetz for OPIE 2.31. Put back manual utmp[x]/wtmp[x]
dnl          checks -- too many OSs can't be trusted to tell us where they are.
dnl	     Check for sys/select.h. Spell endutent right. Replace strtoul()
dnl	     if needed. Removed duplicate check for sysconf. Added check for
dnl          SunOS C2 shadow passwords (may need more work). Replace
dnl          setutent. Added options to disable use of utmp/wtmp. Replace
dnl          seteuid and setegid. Check for usleep. Moved options.h options
dnl          here as enable/disable options.
dnl     Modified by cmetz for OPIE 2.3. Removed redundant memset/memcpy.
dnl	     Changed ls -g test around. Changed logindevperm/fbtab defines.
dnl	     Added check for /etc/environment and /etc/src.sh. Check for
dnl          /var/adm/sulog. Check for {get,put}utxline, provide libmissing
dnl          versionf of {get,put}utline. Added --enable option for anonymous
dnl          FTP. Got rid of a few unneeded checks. Check for functions only
dnl	     used by libmissing only if the replacement function that needs
dnl	     them is itself needed.
dnl	Modified by cmetz for OPIE 2.22. Check for Solaris drain bamaged ls.
dnl          Check for setlogin(). Removed duplicate checks for some funcs.
dnl     Modified by cmetz for OPIE 2.21. Filename must be in utmp[x]/wtmp[x]
dnl          defines.
dnl     Modified by cmetz for OPIE 2.2. Misc changes. Changed for libmissing
dnl          support and building its target object list. Changed to support
dnl          FUNCTION declaration et al. Added a LOT of checks and a LOT of
dnl          fixes.
dnl	Created at NRL for OPIE 2.1.
