Hi Óscar,
Thanks for your elaborate answer. It clears up some questions, but
unfortunately also raises a few:

I didn't set the original value with the Windows-style path, that was done
automatically. I tried the POSIX-style path just to see if it worked. (There's
a StackExchange answer somewhere suggesting this, but I posted here because I
didn't think this was the right way to go about it.)

I had C:/msys64/usr/bin in my system PATH and replaced it with
C:/msys64/mingw64/bin. The only other change I made was to add C:/Program
Files/Git/usr/bin to `exec-path` in Emacs, in order to use git from
<https://gitforwindows.org/>.

I didn't, I installed Emacs from gnu.org (installed to C:/Program\
Files/emacs-27.2-x86_64/). Would there be an advantage in installing Emacs with
pacman instead? Will that give me a graphical Emacs or just a console one?

Any point in installing those given that I didn't install Emacs with pacman?
Can they be used with Emacs from gnu.org?

Currently, after modifying the system PATH as described above, I can install
packages from GNU Elpa again (Melpa was never a problem).

Is there an Emacs 28 pretest available that will work with this? (The Windows
binaries that were anounced on emacs-devel the other day appear to be MSYS2
binaries? And `pacman -Ss emacs` doesn't return any Emacs 28 packages.)

I'm using the latter and added "C:/Program Files/Git/usr/bin" to `exec-path`,
as mentioned above. Wrong decision?

OK, I can try that instead.

I've been using Git Bash (alongside eshell) as my shell of choice. Would the
MinGW-x64 shell provided by MSYS2 be a better choice? Or doesn't it really
matter?
Thanks!
