In the case of cd, I'm not going to patch bash to do this by default.  However, 
you may be able to figure out how to write a shell function that uses bash's 
case-insensitive globbing to get something close to what you want:

$ shopt -s nocaseglob
$ echo src SRC sr[c] SR[C]
src SRC src src

So, given a name you want to normalize, find a way to rewrite it as a shell 
glob (easiest way to avoid the glob expanding into multiple files is converting 
one letter into a one-byte charset).  Seems like it would be an easy sed script 
to write to do that, which in turn can be wrapped by shell functions.  But 
beware that with cygwin 1.7, you can have directories which are case sensitive, 
in which case the glob may return multiple files.
