chmod help

hi, 
i have cygwin 1.3.18 running on win2k. i also have some problems with chmod. 


**$ ls -l
total 1
drwxr-xr-x    2 Administ None            0 Sep 30 20:13 grass.src
-rw-r--r--    1 Administ None            2 Jan 10 09:21 test

**$ chmod +x test

**$ ls -l
total 1
drwxr-xr-x    2 Administ None            0 Sep 30 20:13 grass.src
-rw-r--r--    1 Administ None            2 Jan 10 09:21 test


the chmod did NOT make the file executable. wonder why? i have tried other permutations and combinations, but to no avail. 
thanks for your help, cygwin is really helpful,
