I've read the actual thread on OpenOCD ML, and i've looked at the links pos=
ted
there. I probably should have subscribed to OpenOCD ML, but i'm too lazy to=
 do
so and will write here instead.

Basically, the thread had three participants:

*kristof mulier: wanted to get OpenOCD binaries for Windows, tried MSYS2, b=
ut
didn't get satisfactory results; posted a link to a guide for building Open=
OCD
with MSYS2, written by some 3rd party
*you: posted a link to a guild for building OpenOCD with Cygwin
*Liviu Ionescu: pointed out that you should be using mingw-w64, said that
Cygwin is prehistoric

Liviu Ionescu seems to be a Microsoft fanboy, since he advocated for the us=
e of
WSL (i already said earlier what i think of WSL). However, he wasn't wrong =
when
he said that you should use MinGW. If a piece of software can be built with
MinGW, then you generally should do so, unless there are specific reasons to
avoid that (compatibility, subtle porting bugs, etc). It seems to be the ca=
se
for OpenOCD.

kristof mulier seems to have weak developer-fu, and got a bit confused. The
MSYS2 guide that he used pointed to a MSYS2 package git repo, and kristof
assumed that the repo in question contained OpenOCD source code (which is
supposedly why he was getting an old version of OpenOCD compiled all the ti=
me).
That is not the case[0]. MSYS2 package repo contains small buildscripts for=
 the
appropriate packages. The reason he was getting an old version is that the
version (git revision, in case of OpenOCD-git) is hardcoded into PKGBUILD f=
ile
(which he didn't edit, uncritically following the guide; the author of the
guide didn't concern himself with getting OpenOCD from lastest git master H=
EAD,
and thus didn't mention that detail).

Therefore i still sand on my advice: either cross-compile from Cygwin, or t=
ry
MSYS2 (the irony here is that your Cygwin guide describes *almost exactly* =
how
one can build OpenOCD from MSYS2).

[0]: at least, i assume so; i don't really use MSYS2 repos or its package
manager, therefore i could be mistaken
