I don't think so either. Actually, I tried a snapshot without that
change (I think from 2005-06-08), too, and got the same problem. But
it still is a quite new problem, I think. Maybe two weeks ago, I
believe, make went through without problems.

exec-path's value is 
("e:/cygwin/usr/local/bin" "e:/cygwin/bin" [rest snipped])

I add the Cygwin /bin directories to exec-path in my site-lisp.el. I
do use the first three non-commented lines from
<URL:http://cygwin.com/faq/faq_3.html#SEC63> in order to get
`ediff-buffers', `ispell-buffer' and `M-x shell RET' to work (requires
also the environment variable `ESHELL' set to `bash', see Message-ID:
<address@hidden>). I don't use the other stuff as it
does not seem necessary.

I was scared, too. I try to keep Cygwin as separated as possible from
the rest, that's why it isn't on my Path. But I need it within Emacs,
that's why I do the above.
