-** 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
