default permissions=600, and can't chmod?

[Thomas L Roche <tlroche at us dot ibm dot com>]

I'm helping other members of my workgroup setup Cygwin on their winXP
SP1 laptops (all pretty much like mine) to run an automated build
process (which depends on ssh-agent). At least one person (I'll call
him "Steve" :-) reports the following problems (but another person
currently on vacation may also have this problem), which I haven't yet
examined in detail (but will do tomorrow):

* default permissions are 600. Steve starts up a bash login shell (and
  ~/.bash_profile starts ssh-agent), then runs an ant script that
  checks out files from CVS. The permissions on all created files are
  600. Among the created files are some JARs: when the process
  subsequently tries to

> java -jar foo.jar

  (in the same directory as the jar) it gets the error

> cannot access foo.jar

* user cannot chmod files. When Steve tries to

> chmod 755 foo.jar

  from his shell, the command runs without error, but

> ls -al foo.jar

  shows no change in permissions (still 600).

Steve has a fair amount of Unix experience, but very little Cygwin
experience, and has a fresh (mid-Sep 05) install of Cygwin. I run the
same ant script and don't have this problem, but I've been running
Cygwin lots longer. 

I'm wondering, what might cause this problem? Are there things I
should look for, or should do, when I check Steve's cygwin? Apologies
if this is a FAQ, but I didn't see anything closely related in

Please feel free to reply directly to me as well as the group, and
TIA.
