I see you didn't get an answer.

The answer is:

Use PATH_MAX.  (If you have MAXHOSTNAMELEN but not PATH_MAX, then just
#define PATH_MAX MAXHOSTNAMELEN.)

If PATH_MAX is undefined, use pathconf.  If pathconf returns -1 (as it
will on the Hurd), do it dynamically, with realloc or whatever else is
appropriate.

Of course, it's also reasonable to just always do it dynamically.
