[glibmm] Get rid of some old Autoconf macro cruft

[Daniel Elstner <daniel src gnome org>]

commit 567ef8f6c9c4b2e8282c96e3b3b6b1946630d5ca
Author: Daniel Elstner <danielk openismus com>
Date:   Tue Aug 11 00:43:38 2009 +0200

    Get rid of some old Autoconf macro cruft
    
    * scripts/dk-warn.m4: Delete file, since the functionality is now
    provided by MM_ARG_ENABLE_WARNINGS() from the mm-common module.
    * scripts/docgen.m4: Delete obsolete file.
    * scripts/cxx_std.m4: Remove stray text snippet from the top of the
    file.  Probably a cut'n'paste accident.
    * scripts/cxx.m4 (GLIBMM_MEMBER_FUNCTIONS_MEMBER_TEMPLATES): Do not
    AC_DEFINE to 0 in the else branch, as that will do the wrong thing
    when #ifdef is used instead of #if.
    * scripts/README: Delete file consisting solely of whitespace.
    * configure.ac: Add note on pointless test for namespace std.
