10c4c88 (Allow add_path() to add non-existent directories to the path,
2008-07-21) introduced get_pwd_cwd() function in order to favor $PWD when
getenv("PWD") and getcwd() refer to the same directory but are different
strings (e.g. the former gives a nicer looking name via a symbolic link to
an uglier looking automounted path). The function tried to determine if
two directories are the same by running stat(2) on both and comparing
Unfortunately, stat() does not fill any ino or dev fields in msysgit. But
there is a telltale: both ino and dev are 0 when they are not filled
correctly, so let's be extra cautious.
This happens to fix a bug in "get-receive-pack working_directory/" when
the GIT_DIR would not be set correctly due to absolute_path(".")
returning the wrong value.
