Hi,

when I use 'cp -R' to copy files, I can't access to the target file (I 
have no permission on the target files)

I reproduce this problem with a fresh install of windows 7 and cygwin
my account is a user account (not admin)

from a DOS box, I create c:\test\d1\d2\test.txt

C:\>md test
C:\>cd test
C:\test>md d1
C:\test>md d1\d2
C:\test>echo test > d1\d2\test.txt

from the cygwin console

$ cd /cygdrive/c/test/
patrick AT WIN-K396JDQPSD0 /cygdrive/c/test
$ ll

#
# Why cygwin doesn't display posix permissions ?
#

patrick AT WIN-K396JDQPSD0 /cygdrive/c/test
$ cat d1/d2/test.txt
test

#
# I have no permission on d1/d2/test.txt, but I can 'CAT' it
#

#
# now, I copy the ./d1/* to ./win
#
patrick AT WIN-K396JDQPSD0 /cygdrive/c/test
$ mkdir sub

patrick AT WIN-K396JDQPSD0 /cygdrive/c/test
$ cp -R d1/* sub/

#
# no more posix file permission
#
patrick AT WIN-K396JDQPSD0 /cygdrive/c/test
$ ll sub/
total 0
d---------+ 1 patrick None 0 Mar 20 17:21 d2

patrick AT WIN-K396JDQPSD0 /cygdrive/c/test
$ ll sub/d2/
total 1
---------- 1 patrick None 7 Mar 20 17:21 test.txt

patrick AT WIN-K396JDQPSD0 /cygdrive/c/test
$ cat sub/d2/test.txt
cat: sub/d2/test.txt: Permission denied
#
# but now I can acces the file from cygwin
#

I return to the DOS box

C:\test>type sub\d2\test.txt
Access is denied.

I can't read the file from windows

Of course, I have no problem with cygwin with my XP computer

Any idea ?
