Subject: cvs unable to remove lock directory; rm -r works

Hi,

I've been trying to track this down for a few days, to no avail.
I have a cvs repository on a samba drive.  My OS is Win2k SP2; CYGWIN is
set to "check_case:strict ntsec notitle nosmbntsec".  My cvs is 1.11.0-1
(I tried both the distribution binary and the one built from the source).
I also tried both cygwin-1.3.13-2 and the cvs HEAD.

When I attempt to check in a file, I receive the following message from
cvs:

$ cvs commit -m "" aaaa
Checking in aaaa;
/export/home/igor/testrepository/aaaa,v  <--  aaaa
new revision: 1.9; previous revision: 1.8
done
cvs commit: failed to remove lock dir /export/home/igor/testrepository/#cvs.lock: Permission denied
$

The relevant mount is

$ mount | grep export
\\samba.watson.ibm.com\igor on /export/home/igor type user (binmode)
$

I'm able to manually remove the directory using 'rm -rf'.  Furthermore,
the following program also works:

$ cat > t.c
#include <sys/unistd.h>
void main() {
  const char *dir = "/export/home/igor/testrepository/#cvs.lock";
  int res = rmdir(dir);
  printf ("%d = rmdir(\"%s\")\n", res, dir);
}
$ make t
gcc     t.c   -o t
$ ./t
0 = rmdir("/export/home/igor/testrepository/#cvs.lock")
$

As far as I could see, cvs also uses the rmdir from cygwin1.dll.  Yet it
was unable to remove the directory, for some reason.  Tracing it under gdb
showed that GetLastError after RemoveDirectory() returned 5
(ERROR_ACCESS_DENIED) when called from cvs.

Would anyone have any pointers on how I could debug this further?  Thanks,
	Igor
