Instead of saying everything twice, once for MinGW64 and then for
MinGW, I'd prefer to say it once for MinGW64, and mention MinGW only
in one or two places, where the we explain the difference.  That would
be consistent with our recommendation to use MinGW64 except in rare
exceptions, and will also avoid annoying repetition.

This again treats the two flavors of MinGW as equal, which I think is
not what we want.  My suggestion is to make it shorter and more to the
point by saying something like

  We recommend that you use MinGW64, unless you need to build Emacs
  for running on versions of MS-Windows before Windows 7.

I see no reason to say more or give more detailed list of
considerations.

This looks like unnecessary whitespace change, perhaps caused by
refilling the text?  The newline before the closing "}" of @footnote
is deliberate and shouldn't be removed, as it makes it easier to
realize where the footnote ends.

Is that semi-colon really necessary?  Did the Gnus syntax change?

Is Hunspell offered by MSYS2 a MinGW64 program or an MSYS program?  If
the latter, we should at least warn people about potential issues with
I/O incompatibilities.

Thanks.
