Running autoconf generates configure from configure.in.
Running autoheader generates src/config.in from configure.in.

AC_DEFINE statements in configure.in produce "#define foo"
statements in config.in. Hence the 

AC_DEFINE(HAVE_GNUTLS, 1, [Define if using GnuTLS.])

in configure.in takes care of one of the hand-written sections.

If you really need to put anything beneath the "config_machfile" etc
stuff in config.in, you do it by adding to AH_BOTTOM in configure.in.
But you almost certainly don't need to do this. The code you have
there now has no effect, because nowhere in the C code is `LIBGNUTLS'
expanded, and even if it were, it expands to a shell variable
$(LIBGNUTLS_LIBS) which won't be set. The AC_SUBST(LIBGNUTLS_LIBS)
line handles substituting the necessary value in the Makefiles.
