Subject: [PATCH] common BUGFIX define PATH_MAX if not available

PATH_MAX is optional in POSIX, and thus may not be provided (e.g. on
GNU/Hurd). Provide a fallback definition for it, so the existing code
keeps working for now; include <limits.h> to ensure that PATH_MAX is
available if provided on the current OS/libc.
