| Emacs assumes Posix-compliant APIs wrt UID/GID/EUID. Platforms that
| don't comply with the Posix semantics of these APIs should either
| (a) become more compliant, or (b) modify the Emacs sources with
| platform-specific code or #ifdef's to work around the lack of
| compliance. (Emacs maintainers generally prefer the former
| possibility, for obvious reasons.) All the other platforms do one
| or the other; why should Cygwin be different? why should we change
| long-standing Emacs code because one platform turns out to be non-
| compliant, and the user refuses to work around the problem by
| configuring his system in a slightly different way?
The proposed chnage, by letting the use to control the
prompting/checking behavior, would solve the issue.
As far as I can tell, it wouldn't break anything.
User already has a write access to the device.
Emacs just doesn't know / guesses wrong / environment is complex /
possibly uses wrong methodology (see Ken's notes about using uid, gid
for write access check).
So why not let user to help it to know via variable?
