The posix.1 spec for getcwd says this:
(section 5.2.2.4)For each of the following conditions, if the
condition is detected, the getcwd() function shall return a value
of NULL and set errno to the corresponding value:
[EACCESS] Read or search permission was denied for a component of
the pathname.
The Posix.2 spec for /bin/pwd does not impose the same restrictions ---
/bin/pwd always works (barring disk errors).
