Thanks Volker! That was what I wanted to hear. :)
The inability to build in parallel was what turned us off mingw/msys way
back when you introduced it. Without concurrency, we certainly did not
see any improvement in performance.

It is a long time ago (~2012) that I added and fixed the MinGW/Msys

version, wasn’t really maintained very well, etc...
But things have changed to the opposite since then and we‘ve switched
to Cygwin at least 3 years ago (can‘t find the exact date now).
As far as I know, there haven‘t been any serious users of the
MinGW/Msys build since then. At that time MinGW/Msys had some serious
problems which made it impossible to do parallel builds. Not sure if
that has been fixed by now?
I personally always liked MinGW/Msys compared to Cygwin because of the
(at least in my eyes) more intuitive way of handling Unix/Windows
paths it’s simplicity and speed. I’m not sure however if it is
currently actively supported, and if the old problems have been fixed.
So to finally answer your question :) I don’t think anybody is
currently using the MinGW/Msys build and I doubt that it will work
without bigger adaptions and fixes.

Volker

From the source history, it appears that with JDK9 we dropped
support for msys:
http://hg.openjdk.java.net/jdk/jdk/rev/2a2e56f4c03b
This was committed about 1.5 years ago - are you suggesting that
perhaps we added support for msys2 later on (perhaps unofficial or
undocumented)?
Thanks,

Subject: Is anyone using msys to build OpenJDK?
If anyone is currently using msys to build OpenJDK, I'm curious to
know what version so I can replicate that environment.
As we are trying to add WSL support, we are touching all sorts of
places in configure, and there is a big risk that we break the
existing msys support. I would like to be able to setup an
environment so I can at least do basic verification of such changes.
I know we initially set this up for msys, but later I tried msys2,
which seemed a lot more modern and easy to use. I do remember
there were several options on how to setup it up exactly though.
