Re: find reports an internal system loop on cygdrive

This works - no loop message

Hmm - on my system there /cygdrive is already a real one as evident from 
Windows Explorer (with no cygwin running) and also by doing:

$ cd /cygdrive/c/cygwin
$ ls -l  

and the real cygdrive will show up along with other directories but.... I find 
this interesting and maybe this is the way is should look (don't know):

Note the ls of cygdrive while in directory /cygdrive/c/cygwin results in a 
total of 0 and yet from some other directory an ls of /cygdrive shows all the 
drives.  Seems a little strange to me but I don't know.

I then went closed my cygwin sessions and using Windows Explorer I removed the 
cygdrive real directory from under cygwin and then opened a couple sessions 
again.  Now when I cd to /cygdrive/c/cygwin and do an ls there is no cygdrive 
directory so we are using the virtual directory.

Now when I do the find I do *not* get the internal loop error:

It appears the real directory is what causes the internal loop error.
