65 # Darwin's getcwd(3) (which Cwd.xs:bsd_realpath() uses which
66 # Cwd.pm:getcwd uses) has some magic related to the PWD
67 # environment variable: if PWD is set to a directory that
68 # looks about right (guess: has the same (dev,ino) as the '.'?),
69 # the PWD is returned. However, if that path contains
70 # symlinks, the path will not be equal to the one returned by
71 # /bin/pwd (which probably uses the usual walking upwards in
72 # the path -trick). This situation is easy to reproduce since
73 # /tmp is a symlink to /private/tmp. Therefore we invalidate
74 # the PWD to force getcwd(3) to (re)compute the cwd in full.
75 # Admittedly fixing this in the Cwd module would be better
76 # long-term solution but deleting $ENV{PWD} should not be
77 # done light-heartedly. --jhi
