        * acincludde.m4: Rename to ...
        * m4/jh_path_xml_catalog.m4: ... this.

        * m4/*.m4: Remove all autoconf m4 files.

Remove old autoconf m4 files from CVS, autogen.sh will now copy current
versions from the system. (Avoid having old buggy versions forever).

-dnl Macro to add for using GNU gettext.
-
-dnl Usage: AM_GNU_GETTEXT([INTLSYMBOL], [NEEDSYMBOL], [INTLDIR]).
-dnl INTLSYMBOL can be one of 'external', 'no-libtool', 'use-libtool'. The
-dnl    default (if it is not specified or empty) is 'no-libtool'.
-dnl    INTLSYMBOL should be 'external' for packages with no intl directory,
-dnl    and 'no-libtool' or 'use-libtool' for packages with an intl directory.
-dnl    If INTLSYMBOL is 'use-libtool', then a libtool library
-dnl    $(top_builddir)/intl/libintl.la will be created (shared and/or static,
-dnl    depending on --{enable,disable}-{shared,static} and on the presence of
-dnl    AM-DISABLE-SHARED). If INTLSYMBOL is 'no-libtool', a static library
-dnl    $(top_builddir)/intl/libintl.a will be created.
-dnl If NEEDSYMBOL is specified and is 'need-ngettext', then GNU gettext
-dnl    implementations (in libc or libintl) without the ngettext() function
-dnl    will be ignored.  If NEEDSYMBOL is specified and is
-dnl    'need-formatstring-macros', then GNU gettext implementations that don't
-dnl    support the ISO C 99 <inttypes.h> formatstring macros will be ignored.
-dnl INTLDIR is used to find the intl libraries.  If empty,
-dnl    the value `$(top_builddir)/intl/' is used.
-dnl
-dnl The result of the configuration is one of three cases:
-dnl 1) GNU gettext, as included in the intl subdirectory, will be compiled
-dnl    and used.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 2) GNU gettext has been found in the system's C library.
-dnl    Catalog format: GNU --> install in $(datadir)
-dnl    Catalog extension: .mo after installation, .gmo in source tree
-dnl 3) No internationalization, always use English msgid.
-dnl    Catalog format: none
-dnl    Catalog extension: none
-dnl If INTLSYMBOL is 'external', only cases 2 and 3 can occur.
-dnl The use of .gmo is historical (it was needed to avoid overwriting the
-dnl GNU format catalogs when building on a platform with an X/Open gettext),
-dnl but we keep it in order not to force irrelevant filename changes on the
-dnl maintainers.
