The DLL load path is set very early in the startup sequence of Windows
programs AFAIK, so I wouldn't expect anything in .emacs to affect it.

It needs to be set outside of Emacs, either by setting PATH system-wide,
or by adding a DllPath for emacs.exe in the registry (I forget the
details of how this is done, Lennart Borgman introduced the idea to me
some years ago, and I think addpm.c might do this for some of the GTK
image libraries).

I took it to mean something else (the .a or .lib files from gnutls/lib
being put into emacs/bin), which will also be ineffective.

What is needed is to put the DLL files from gnutls/bin into emacs/bin
if you want to get this working without messing with PATH.

The directory in which an .exe resides is first in the DLL load path by
default, regardless of whether it is in your PATH.
