    aclocal: diagnose non-existing directories in AC_CONFIG_MACRO_DIR better
    
    This new implementation ensures that any directory (possibly excluding
    the first one, if the '--install' option is used) that is declared with
    AC_CONFIG_MACRO_DIR and that is non-existent will cause an error from
    aclocal.
    
    * aclocal.in (scan_m4_dirs): Add a new argument, telling whether it's OK
    for the scanned directory to be non-existing.  Adjust the implementation
    accordingly.
    ($first_user_m4dir): Remove, no more needed.
    (scan_m4_files): Update 'scan_m4_dirs' invocations so that aclocal will
    not complain if the first user macro directory is non-existing and the
    '--install' option is given: such directory will be created later by
    aclocal itself.
    * t/aclocal-macrodir.tap: Do not mark the last test as TODO anymore;
    it now passes.  Make stricter by ensuring a non-existing directory in
    AC_CONFIG_MACRO_DIR causes an hard error, not a warning.

commit e8edece53fd6e71ae3a05a0e266be06ab4f38668

    aclocal: multiple local m4 macro dirs with AC_CONFIG_MACRO_DIR
    
    It can be done either passing several arguments to a single invocation:
    
        AC_CONFIG_MACRO_DIR([dir1 dir2])
    
    or issuing more invocations:
    
        AC_CONFIG_MACRO_DIR([dir1])
        AC_CONFIG_MACRO_DIR([dir2])
    
    This will allow projects to use several m4 macro local dirs.  This is
    especially important for projects that are used as nested subpackages
    of larger projects.
    
    Autoconf will soon follow suit, with a new macro AC_CONFIG_MACRO_DIRS.
    Once that has been implemented in their git repo, we will start to
    support it as well.

    * aclocal.in ($ac_config_macro_dir): Turn this global scalar it into ...
    (@ac_config_macro_dirs): ... this global array.
    (trace_used_macros): Update '@ac_config_macro_dirs' instead of re-defining
    '$ac_config_macro_dir'.  Cater to multiple arguments in AC_CONFIG_MACRO_DIR
    and to multiple AC_CONFIG_MACRO_DIR invocations.
    (main loop): Append '@ac_config_macro_dirs', not '$ac_config_macro_dir',
    to '@user_includes'.
    * t/aclocal-macrodir.tap: Extend and enhance.
    * t/subpkg-macrodir.sh: New test.
    * t/list-of-tests.mk: Add it.
