   1 /* c-pathmx.h: define PATH_MAX, the maximum length of a filename.
   2    Since no such limit may exist (pace GNU Hurd), these constants should
   3    not actually be used; filenames should be dynamically grown as
   4    needed.  Most of Kpathsea does this now, but not all, and not all
   5    programs using it.
