Please note that they don't need to _add_ makeinfo.bat, they just need to
have it in the binary distro.  makeinfo.bat (and a couple of other Windows
batch files) are part of Texinfo sources, I added them to the upstream
Texinfo many years ago.  What MSYS2 folks need to do is to provide a mingw
port of Texinfo, not an MSYS2 port, and then "make install" will install the
batch files.
