I don't like this solution.  The root cause is that apparently MSYS2 doesn't
provide a functional native Windows port of Texinfo that works outside of
MSYS2 Bash.  It is not hard to provide such a port, and the proof is here:

  https://sourceforge.net/projects/ezwinports/files/texinfo-6.8-3-w32-bin.zip/download

So if MSYS2 folks don't get their act together soon, you may wish trying the
above port, which works for me on MS-Windows very well without any problems
(and I build Emacs all the time, as you may guess).  It is a 32-bit port,
not a 64-bit port, but I don't think this should matter for your purposes.

(And if you must have the latest Texinfo 7 instead of 6.8, just wait for a
few days.)

But tweaking Emacs because of this is IMNSHO a kludge, especially since a
simple solution is already available.  So I don't think we should do this.
