	PATH_MAX is not defined on systems which have no limit on filename length,
	such as GNU/Hurd.

	This file does not define PATH_MAX always. Programs that use this file
	can handle the GNU/Hurd case in several ways:
	- Either with a package-wide handling, or with a per-file handling,
	- Either through a
	#ifdef PATH_MAX

	#endif
	or through a fallback like
	#ifndef PATH_MAX
