That must have got saved as an option somewhere, maybe I can still find an old enough backup to compare the startup files to.

Re: cygwin Digest 17 Jun 2017 08:20:29 -0000 Issue 10294
I am new to *writing* to mailing lists so if I've done something wrong
please forgive me.
I would like to "cygport" the Mudlet GPL MUD {Multi-User Dungeon} client
to Cygwin - I have a cygport file (and currently a patch) that works to
compile a workable binary of the 3.1.0 release available as a tarball
from https://github.com/Mudlet/Mudlet/archive/Mudlet-3.1.0.tar.gz {other
distribution methods are available!} but Mudlet possesses a Lua
sub-system that users/MUD system operators can use to provide additional
functionality and this is currently proving awkward!
The issue I am having is that Mudlet needs some Lua "modules" to operate
and Cygwin currently only provides a sub-set of the needed ones, the
lua-file-system "lfs" IS available but also needed is:
* "rex_pcre"
* "zip"
* "luasql.sqlite3"
What is the best way to get those "run-time" dependencies into Cygwin? I
have found "luarocks" packaged versions (as "lrexlib-pcre", "luazip" and
"luasql-sqlite3" respectly) but it is not immediately apparent how I
might use that to generate the things needed as part of the "cygport"
process.
For the record Mudlet {https://www.mudlet.org} is carried on, at least,
the Debian & Ubuntu GNU/Linux distributions and it's developers do
target and aim to provide Linux, macOs and Window platform binaries as
well as source code. However the Windows one does suffer a little in
bug-fixes and performance because it is difficult to put together a
development platform (IMHO) for that OS that will work in both a 32 and
a 64 bit environment (as until very recently) the Qt people only made a
32 bit FOSS development environment available with a built-in Mingw
compiler and, of course, the alternative free MSVC compiler can not be
used to make binaries that can be distributed under GPL terms; the need
to compile/source the other libraries that Mudlet uses in a form that is
compatible with anything compiled with such a Qt/Mingw combination makes
the Cygwin environment much more user friendly for normally *nix system
based developers...
I should perhaps point out that I *am* one of the "upstream" i.e. a
member of the team that call ourselves the "Mudlet-makers" and I have
been using Cygwin on and off for years now... 8-)
I do miss the Qt Creator IDE when I switch to the Cygwin environment
though. 8-(

If you try this in emacs-nox in Mintty with TERM=xterm-256color, you'll see that white is #e5e5e5 and brightwhite is #ff. So I guess there's no bug here, just a surprising definition of "white".

I already said in my original report that I can reproduce this from my Linux box via konsole.

Sorry, I misunderstood what you meant by "Cygwin update". I understand now. I'll try to do a bisection of the Cygwin sources. It may be a few days before I get to this. It may be possible that the coreutils update messed up things in a way that I don't understand, but that's unlikely. Or vim might have delivered a file that conflicts with something from Emacs, but Emacs has since been updated again and so that conflict would have flipped in favor of Emacs at those times, which I didn't observe (and no such conflicts seem to exist in the package file listings at the current moment). I just tried downgrading cygwin1.dll to the 2016-12-14 snapshot, emacs to 25.1-1 (released 2016-09-17), and coreutils to 8.26-1 (released 2016-12-16). The problem is still there with that configuration. And starting with an off-white background is not necessary. Even with no .minttrc, 'emacs-nox -Q' followed by 'M-x set-background-color RET white RET' turns the background gray. I can also reproduce the problem in xterm, so I don't think Mintty is the culprit. What about ncurses? That was updated on 2017-01-27? I haven't tried downgrading it yet, but I can probably try it later today.
