This fix should be pushed to older Fedora versions updates as well.

Could you please include this patch as well - https://mail.gnome.org/archives/mc-devel/2017-April/msg00006.html ? Without it the filestamps of files copied from tar.gz, cpio, are not preserved (see https://mail.gnome.org/archives/mc-devel/2017-April/msg00000.html).

I'll busy for next 2 days. Hopefully rel 2 with reverte to use slang will be released soon because this is now more important.
Will try to have look later on this.

PS. I have no RW access to mc but I can help maintain it as my admin access request will be approved.

4.8.19-2 mc.spec.patch

corrected typo.

Hellow. Can I have any feedback from maintainer?
Current binary mc package has an issue which needs to be sorted out ASAP!!!

any progress on this?

Note that you need to use "%bcond_with ncurses" if you want to
avoid ncurses by default :-)

Also the use of "with_ncurses" macro may not be right.  Was the
build even tested?

http://rpm.org/user_doc/conditional_builds.html

It was tested seems you wrote your comment without testing.
"%bcond_without foo" enables it. Yes, it is illogical but it works exactly this way and it works completely opposite to --with{,out} foo cmd switches.
First found example abrt.spec. You can find in it 

%if 0%{?fedora} >= 14
    %bcond_without systemd
%else
    %bcond_with systemd
%endif

and as you see "%bcond_without systemd" enables by default build abrt with systemd support on fedora>=14
Because %bcond has been introduced +12 years ago now is to late to reverse how it works because it will break thousands of specs files.

If the purpose is that "without ncurses" is the default, it should
really be:

> %bcond_with ncurses

because otherwise (bcond_without), "with_ncurses" gets normally
(with non-opinionated "rpmbuild" run) defined and you will end
up building with ncurses, which against the intent of this bug?

You should also be crafting binary either-or strings like this:

> %{?with_ncurses:ncurses-devel}%{!?with_ncurses:slang-devel}

Note that passing --with/--without to rpmbuild does not count, it
will not get called like this in koji build.

Nope, I haven't tested that myself, but I don't lack packaging
experience either.

I'm confused a bit. So what you are doing here?
Please do this first and then try to discuss anything.
If you are not familiar with %bcond (and seems you are because you didn't know that "%bcond_without foo" enables foo) please do not ask me to elaborate how macros created by %bcond are working. RTFM.
If it is not clear this %bcond is not for automated build over koji but for developers able to diagnose ncurses ot term applications issues which mc exposes by compiling with ncurces.

mc.spec.patch

I must apologize Jan. He was right about my mistake in %bcond logic in my patch.
Simple I've attached incorrect version of the patch.
I've changed %bcond name to "%bcond_without slang" to make it less confusing that slang is default screen type.

No problem, glad that point was taken :)
