/usr/bin exists not; man can't find nroff; permissions inconsistent

[Carlo Florendo <list-subscriber at hq dot astra dot ph>]

Hello,

After installing cygwin, I am encountering some issues.  cygcheck's 
output attached:

First, I tried to man bash.  Nothing appeared on screen so I hit `q'.  
Then, it says that nroff was not found.

$ man bash
/usr/bin/nroff: not found

Then,  I checked whether nroff existed:

$ ls -l /usr/bin/nroff
-rw-r--r--    1 Carlo    None         1955 Dec 16  2002 /usr/bin/nroff

Thus, I thought it existed but the permissions were not set well.  I 
then tried to change the permissions:

$ chmod 755 /usr/bin/nroff
chmod: changing permissions of `/usr/bin/nroff': No such file or directory

As you see, it says that the file does not exist.  Strange, isnt't it?  
Then, I tried catting the file. Here's what I got.

$ cat /usr/bin/nroff
cat: /usr/bin/nroff: No such file or directory

Thus, I tried going to the /usr/bin directory itself and catted nroff to 
see if it really existed:

$ cd /usr/bin

$ ls -l nroff
-rwxr-xr-x    1 Carlo    None         1955 Dec 16  2002 nroff

$ cat nroff
#!/bin/sh
# Emulate nroff with groff.

prog="$0"
# Default device.
# First try the "locale charmap" command, because it's most reliable.

<Rest of output snipped>

Thus, it exists.
Then, I again tried doing an `ls -l' on nroff, first *not* specifying 
its fully qualified name (FQN), and afterwards, specifying its FQN.  
Here's what I got:

$ pwd     
/usr/bin

$ ls -l nroff
-rwxr-xr-x    1 Carlo    None         1955 Dec 16  2002 nroff

$ ls -l /usr/bin/nroff
-rw-r--r--    1 Carlo    None         1955 Dec 16  2002 /usr/bin/nroff

As you can see, the first listing says the permission is a 755.  The 
second listing says the permission is a 644.   This seems to me 
strange.  Why does the permission for the same file appear differently 
when accessed via different means.  (i.e. specifying its FQN; not 
specifying its FQN)?

Thus, I thought that /usr/bin/nroff was probably hardlinked from 
/bin/nroff and that this linking might have caused some problems so I 
checked out /bin/nroff.  /bin/nroff existed.  I found out that 
/usr/bin/nroff is indeed a hardlink to /bin/nroff but I didn't see why 
this could really cause a problem.

Then, I tried opening a cmd prompt to check if there is any clue I could 
get from it. 
This is what I got:

The directory d:\cygwin\usr\bin does not exist. (i.e. It is neither 
listed with `dir /w' nor `dir bin' nor `dir d:\cygwin\usr\bin') It 
appears to be linked somewhere else. 


I would appreciate it very much if anyone could point out which part of 
the source code I could tweak.  I'd like to learn diagnosing problems in 
source code level. 

Another thing to note is that cygcheck reports several warnings of this 
sort:

Found: d:\cygwin\\bin\ls.exe
Found: d:\cygwin\bin\ls.exe
Warning: d:\cygwin\\bin\ls.exe hides d:\cygwin\bin\ls.exe

What could be the problem on my system?  I know I'm  missing something.

Thank you so much!

Best Regards,

Carlo
