Yes, I agree completely.  The issue is implementation.  Simply using the 
NORM_IGNORESYMBOLS flag yields comparison functions that can return 0 on 
unequal strings.  Eric pointed out the problem with that; moreover, it 
seriously violates users' expectations and compatibility with glibc.  I 
thought I had a way around that, but Corinna pointed out in 
https://www.cygwin.com/ml/cygwin/2015-10/msg00559.html why my suggestion 
doesn't work.  At this point I'm out of ideas.
