"during startup" is a little fuzzy; if Emacs is looking for gnutls
before processing init.el, then this PATH change won't have an effect.

In addition, at some point during startup, Emacs copies the value of
PATH into exec-path; that is the path used by Emacs itself when
searching for executables (and, I assume, DLLs). I always set exec-path
first, then set PATH from it:

  (setq exec-path
        (list
         (expand-file-name "~/bin")
         (concat "/Apps/GNAT-" (getenv "GNAT_VERSION") "/bin")
         "c:/Apps/android/android-sdk/tools"
        ...))

  (setenv "PATH" (mapconcat 'identity  exec-path  path-separator))

In any case, try setting PATH in your .bash_profile, so it is correct
before starting Emacs.

This is unclear. If emacs.exe is in 

c:/stuff/emacs-24/bin/emacs.exe

this seems to say you put gnutls.dll in 

c:/stuff/emacs-24/lib/gnutls.dll

Better would be:

c:/stuff/emacs-24/bin/gnutls.dll

but that only helps if emacs-24/bin is in your PATH before emacs starts;
it does not need to be to start emacs.
