Right. Thanx. I wondered why the "a" got up-cased.

I suppose one could argue that, by using -w, that cygpath might assume that it 
is converting *from* a POSIX path, and therefore the colon would not indicate 
a drive letter--wouldn't that make sense?--but I’ll let someone else take up 
that battle. ☺

Also, in the following, I would expect cygpath to figure out that I *am not* 
specifying a drive letter:

$ cygpath -w ./a:b | od -An -tx1c
  41  3a  62  0a
   A   :   b  \n
$

But I don't have a dog in this fight, either.

(Replying to a direct reply from Mr. Repin rather than from the list, so hoping
this doesn't break message threading.)
