It's just a hint. To be precise, get_pwd_cwd() _does_ stat() what's in PWD, and _does_ compare with the stat() of what comes out of getcwd(), but that comparison uses only st_dev and st_ino, both of which happen to be 0 in my case -- for each and every file/directory. I can only _guess_ at the reasoning behind get_pwd_cwd(). I _think_ it was meant to catch the case when getcwd() and PWD refer to the same directory, but PWD goes through symbolic links. I was tempted to just throw that PWD handling out for Windows, since we do not have symbolic link handling yet. But that is currently actively discussed, so we might need it in the future, in which case I have to figure out how to fake reliable st_dev and st_ino values into our stat() code.
