B20.1 on NT4.0SP5: remove() and unlink() don't return an err

I tried to remove() and unlink() files in write-protected directories, where
files cannot be removed.
(1) C:\TMP\X\ is local on NTFS protectet by NTFS security (I'm a local admin)
(2) V:\WINNT\JAVA\ is remote on a NetWare drive (where I'm not admin)
(3) J:\MQF\X\ is on a remote Samba Drive (where I'm not admin)
In cases (1) and (2) remove() and unlink() don't return an error !
The files are not removed though (they can't). Surprisingly in case (3) they do
return an error !
I think it's because dirs (1) and (2) appear to cygwin to be writable whereas
(3) appears to be readonly.
The sample code I used:
#include <stdio.h>
#include <unistd.h>
void main(int argc, char ** argv) {
int i;
for (i=1; i<argc; i++) {
if ( remove(argv[i]) ) perror(argv[i]);
else printf("%s remove()'d\n",argv[i]);
if ( unlink(argv[i]) ) perror(argv[i]);
else printf("%s unlink()'d\n",argv[i]);
if ( !fopen(argv[i],"r") ) perror(argv[i]);
else printf("%s still there\n",argv[i]);
}
}
I compiled it with "gcc -ormx rmx.c"
The output I get is:

The snapshot cygwin1.dll from Feb. 25, 2000 seems to behave better, (but I
can't compile with it) :
C:\TMP\x>copy c:\cygnus\CYGWIN~1\H-I586~1\bin\cygwin1.200002.dll
c:\winnt\system32\cygwin1.dll

---------------------------------
Is there a stable cygwin1.dll with this bug fixed ?
