Heh.  I just looked, and it seems you've never posted the output of
"cygcheck -svr" on your system as requested in

> Problem reports:       http://cygwin.com/problems.html

I bet that if you did post one, it would show that your Cygwin is
installed on either FAT or FAT32, not NTFS.  That, and the DOS "Read-only"
bit on the directory is probably set.  Another (less likely) alternative
is that you've installed on a network drive.

If it's FAT32, you're out of luck.  In other cases you would probably
benefit from reviewing <http://cygwin.com/cygwin-ug-net/ntsec.html>.
