Greetings, Dmitry Katsubo!

Dear Cygwin community,

I observe the following on my Cygwin:

This is not cygwin, this is bare Windows.

That may be so, yet there may be an issue here for someone packaging
Cygwin programs for use as native Windows applications.

That is to say, there could potentially be something here that the Cygnal
project could address:

Cygnal is an ultra-light fork of the Cygwin DLL that is intended for users like Dmitry Katsubo, who run Cygwin programs out of the Windows environment directly, after building them in Cygwin.


when I put quotes around file that has
non-ASCII symbols, these quotes are passed to argv of the process literally, otherwise they are removed. I would expect that there is a consistency.

Parameter unquoting done by the shell.
CMD does that differently from POSIX shells.

As I seem to recall, CMD doesn't do anything, period! It passes the command line
as one big string. It has to since that's the OS mechanism.

The quoting conventions come from how various run-time libraries deal with that string. An influential convention is that of the MS Visual C run-time library; it behooves other run-times to be compatible with that for consistency with
programs whose main() was compiled with MSVC.
