I assume the following two:
(1) You are using git for windows which enables autocrlf feature.
(2) You built AUCTeX on a local copy of git repository.
(Actually I couldn't reproduce the problem by just copying the files to
my windows 10 and running configure and make with msys. It's only after
a web search with the keywords "local variables entry is missing the
suffix" that I realized what's going on by references such as:
https://github.com/hlissner/doom-emacs/issues/2637
https://github.com/raxod502/straight.el/issues/346
https://github.com/tumashu/helm-posframe/pull/9
https://github.com/ikirill/irony-eldoc/pull/13
)
The autocrlf feature silently converts the eol of the files in the
working directory from LF to CRLF, which ends up with contradicting
coding: tag specified in tex-jp.el.

I think that the proper approach for this issue is to turn off the
autocrlf feature for at least the local AUCTeX repository, but at the
same time think that it isn't bad to make AUCTeX more generous to
loosely configured local git repos. I'll remove eol suffix from coding:
tag.

I don't think it's windows unfriendly. As stated above, the current tag
coding: iso-2022-jp-unix
works fine even on windows if the file is copied as-is, without eol
format conversion. In my opinion, it's more of the problem on the side
of git for windows, with respect to the status of autocrlf feature.
