All the features in this patch (except for the "noacl") do not require any 
configuration, since there is no 'loss of behavior' or 'loss of correctness'. 
st_ino, st_nlink behave as before. Symlink and executable script detection 
behave as before (just faster...).

Yoni is preparing a patch to submit that will not include the noacl feature, and 
thus will not include any CYGWIN env related stuff.
