-**  MAXPATHLEN and PATH_MAX
-**
-**     On most systems MAXPATHLEN is defined in sys/param.h to be 1024. Of
-**     those that this is not true, again most define PATH_MAX in limits.h
-**     or sys/limits.h which usually gets included by limits.h. On the few
-**     remaining systems that neither statement is true, _POSIX_PATH_MAX 
-**     is defined.
-**
-**     So:
-**         1. If PATH_MAX is defined just use it.
-**         2. If MAXPATHLEN is defined but not PATH_MAX, then define
-**            PATH_MAX in terms of MAXPATHLEN.
-**         3. If neither is defined, include limits.h and check for
-**            PATH_MAX again.
-**         3.1 If we now have PATHSIZE, define PATH_MAX in terms of that.
-**             and ignore the rest.  Since _POSIX_PATH_MAX (checked for
-**             next) is the *most* restrictive (smallest) value, if we
-**             trust _POSIX_PATH_MAX, several of our buffers are too small.
-**         4. If PATH_MAX is still not defined but _POSIX_PATH_MAX is,
-**            then define PATH_MAX in terms of _POSIX_PATH_MAX.
-**         5. And if even _POSIX_PATH_MAX doesn't exist just put in
-**            a reasonable value.
-**         *. All in all, this is an excellent argument for using pathconf()
-**            when at all possible.  Or better yet, dynamically allocate
-**            our buffers and use getcwd() not getwd().
-**
-**     This works on:
-**         Sun Sparc 10        SunOS 4.1.3  &  Solaris 1.2
-**         HP 9000/700         HP/UX 8.07   &  HP/UX 9.01
-**         Tektronix XD88/10   UTekV 3.2e
-**         IBM RS6000          AIX 3.2
-**         Dec Alpha           OSF 1 ????
-**         Intel 386           BSDI BSD/386
-**         Intel 386           SCO OpenServer Release 5
-**         Apollo              Domain 10.4
-**         NEC                 SVR4
