Interesting.  I get the desired results if I change the NTFS permissions
for the folder to "Everyone (Read & Execute)".  After that one change,
all existing files in the folder now show up 0755 instead of 0700.

Doing a Cygwin "chmod 0755" on the folder had no effect on inherited
permissions, but DID change the permissions shown by "ls -ld ."

Does Cygwin store its own "override" permissions if you use the chmod
command?
