They have to be executable, not readable.  The readable bit controls
listing the contents of the directory, but accessing the files requires
the directory to be executable.

All of the above have to be readable, too.

Of course it wouldn't.  Cygwin uses Winsock, which looks for the files in
the above directory, not in /etc.  The /etc links are simply to make
Cygwin look more like Linux.
