Rob,
Actually, this behavior also depends on the filesystem you use.
CYGWIN=ntsec alone only helps if you have NTFS. For FAT you also need
"ntea" (i.e., CYGWIN="ntsec ntea" -- be aware that it'll create a large
file in your drive's root directory). I believe permissions on FAT32 were
broken somehow, but don't recall the details -- just search the archives
for "FAT32 ntea".
