You shouldn't care generally, and if you do, network-stream.el should
provide the necessary introspection.  So I'll provide whatever
information network-stream.el needs, but want to avoid making gnutls.el
a standalone networking library.

JB> Oh, that function is just

DEFUN ("gnutls-available-p", Fgnutls_available_p
       Sgnutls_available_p, 0, 0, 0,
       doc: /* Return t if GnuTLS is available in this Emacs session.  */)
  Lisp_Object found = Fassq (Qgnutls_dll, Vlibrary_cache);
  if (CONSP (found))
    return XCDR (found);
    return init_gnutls_functions () ? Qt : Qnil;
  return Qnil

I think that would return Qnil for non-WINDOWSNT cases?  And maybe it
should be called gnutls-dll-available-p, so then we can say

(defun gnutls-available-p ()
  (and (gnutls-dll-available-p)
       (fboundp 'gnutls-boot)
