Hi all,

I just updated from cygwin 1.7.32 to 1.7.35,
and now file permissions are calculated differently,
which breaks fetchmail for me:

Here are the Windows permissions:
(no permissions for Domain Users / Dom=E4nen-Benutzer)

$ cacls fetchmailrc.txt
D:\fetchmail\fetchmailrc.txt NT-AUTORIT.T\SYSTEM:(ID)F
                              NT-AUTORIT.T\LOKALER DIENST:(ID)C
                              DOMAENE\LocalAdmin:(ID)F
                              VORDEFINIERT\Administratoren:(ID)F

cygwin-1.7.32 $ ls -l
-rwx------+ 1 LocalService Dom=E4nen-Benutzer    1932 15. Aug 2014=20
fetchmailrc.txt

cygwin-1.7.35 $ ls -l
-rwxrwx---+ 1 LocalService Dom=E4nen-Benutzer    1932 15. Aug 2014=20
fetchmailrc.txt


Now, there are group permissions set. For me it breaks fetchmail,=20
because fetchmail only runs when the config file is owned by the user=20
running fetchmail (LocalService in my case, a system user I never can=20
login with) and with max 0700 permissions. While this check is ok/good=20
for Unix, because you still can view/edit the file as user root, you=20
now can't anymore as Administrator on Windows.


So cygwin's old calculation helped me to get it working that both=20
fetchmail is happy as the file is only accessible by the user running=20
fetchmail and I am happy to be able to change the file as=20
Administrator. This seems now broken, or is there still a possibility=20
to do that?


@fetchmail's maintainers:
Is it possible/desired/ok to disable this check on Cygwin?


Thanks
Martin=
