I doubt many have noticed, but GNU pwd would fail when run from a
working directory whose absolute name is longer than PATH_MAX.
This came down to a limitation in most (all?) implementations of
the getcwd function. That includes Linux-2.6.x w/glibc-2.3.2,
Solaris 5.9, FreeBSD 5.0, NetBSD 1.6. Maybe the Hurd lacks this
limit?
Yup, it lacks it. See [libc]/sysdeps/mach/hurd/getcwd.c.
