    David> Is there some recent Cygwin feature change that could be causing this?

I discovered that if I change my CYGWIN variable from "tty" to "tty nontsec"
this now behaves as I would expect, showing a read-only buffer for a read-only
file.

Before discovering this, I also noticed that if a file only had the "read" bits
on, then XEmacs would see it was read-only.  However, if the file had both the
read AND execute bits on (still not having any write bits), then XEmacs would
think it was writable.

Testing the same situation with "vi" showed a read-only buffer, both before and
after changing the CYGWIN variable.
