Thanks!  But I'm not quite there yet.  I found

  mingw-w64-x86_64-gnutls

and installed it:

Then I looked at all DLLs that all packages bring:

%pacman -Ql mingw-w64-x86_64-gnutls mingw-w64-x86_64-nettle

I copied them all to c:/sys/emacs/bin, where my emacs.exe lives:

--8<---------------cut here---------------start------------->8---
%pwd
c:/sys/emacs/bin

%ls -l emacs.exe
-rwxr-xr-x 1 x 6459904 Aug 21  2020 emacs.exe

%echo $p

I ran another emacs instance (through runemacs.exe), but 

  gnutls-available-p

still produces nil.
