For starters, http://cygwin.com/acronyms/#PPIOSPE.  Not to sound mean, but
I will not answer any more of your emails sent directly to me in regards
to cygwin questions; I will only answer emails sent to the list (assuming
I have an answer).

It sounds like your chmod is having problems with permissions, just like
the rest of your emails to the list about installation problems have
hinted at.  Somehow, the user id you are running as under cygwin does not
have the same rights to edit a file as when you create files using Windows
means, which means that somewhere in your file system hierarchy, there is
a strange or restrictive permissions setting.  And if /etc/group and
/etc/passwd don't recognize your user and group names yet, you are also
going to have problems.

I'm not an expert at ACLs, but a good test case that someone on the list
might be able to help you debug is if you were to post a side-by-side
example of two files, one where you can chmod and the other where you
can't, along with the output of getfacl for those two files and
recursively up the hierarchy for every directory that contains those two
files, as well as the output of id.
