Execute permissions alone should be sufficient to start an executable,
usually.
That's a bug in Cygwin. The code spawning a new process tries to open
the executable for reading to find out if it's a Cygwin executable,
a native Windows executable, or a script. The problem is that the code
assumes non-executablity if the couldn't be opened for reading and
returns an error.
I applied a patch which checks if the file couldn't be opened due to
an ACCESS_DENIED. If so, it checks explicitely for executability.
If the file is executable, it just assumes a Cygwin executable now.
This won't work nicely for native executables, but a file which is
non-readable but executable is rather unlikely on the native Win32
level.
