You've installed the wrong package: the above is the MSYS GnuTLS,
whereas you need MinGW port of GnuTLS.  Look for a package with
"mingw" in its name.

To install, put the DLLs in the package either in the same directory
where you have the emacs.exe executable, or somewhere on your Path.

Yes, because the native Windows build of Emacs cannot use MSYS DLLs,
it must have MinGW DLLs.
