    On some distributions tools like cpp are prefixed with the host-triple,
    to check for this prefixed version first AC_PATH_TOOL should be used. If
    no prefixed cpp, it will fallback to the unprefixed name.

    Rework CHANGELOG_CMD to touch/echo >&2 only as needed
    
    Currently CHANGELOG_CMD issues a
    
      touch ChangeLog; echo "Scary message" >&2
    
    even if the file is already present. For example, when running `make
    distcheck' the following is observed:
    
    "
    /bin/sh: ../../.changelog.tmp: Permission denied
    git directory not found: installing possibly empty changelog.
    ...
    /bin/sh: ../../.changelog.tmp: Permission denied
    git directory not found: installing possibly empty changelog.
    "
    
    That in itself happens since srcdir is RO, thus shell redirection [to
    srcddir/.changelog.tmp] fails. At the same time the latter message is
    wrong and misleading since the file is already there, with the correct
    contents.
    
    Silence the permissing warning (/dev/null is our friend), and add
    a simple `test -e .../ChangeLog || (...' prior to the touch/echo combo.
    
    As we're here also update the message to be more generic, since there
    are multiple other reasons why things can fail.

    Fix XORG_WITH_XMLTO to work with xmlto >= 0.0.27
    
    Starting with xmlto version 0.0.27 the return code of
      xmlto --skip-validation txt conftest.xml
    is non-zero if conftest.xml is an empty file.
    
    As a consequence the macro XORG_WITH_XMLTO returns
      "xmlto cannot generate text format, this format skipped"
    and therefore libraries like libxi, libxdmcp and others won't convert
    docbook XML to text format.
    
    This changed behavior was introduced with the following change in xmlto:
      xmlto.in: use correctly exit code from xsltproc
    See also: https://fedorahosted.org/xmlto/changeset/77
    
    This patch fixes this by additionally testing xmlto with a non-empty XML
    file.
    
    More details can be found at:
    https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=613674
    
    Thanks to Peter Pearse, Helmut Grohne and Gaetan Nadon.
    
    v2: To maintain compatibility with older xorg tarballs don't replace
        the original test with the empty XML file but instead add a fallback
        to additionally test with a non-empty XML file if the original test fails.
        Use the alternate solution with <x></x> to skip compatibility issues
        with different docbook versions.

    XORG_PROG_RAWCPP: Add TRADITIONALCPPFLAGS
    
    In some cases we may want to have -traditional for proper whitespace preserving
    without -undef, as we actually want the system definitions to be in place
    so we can #ifdef on them. IE in xinit various .cpp files contain things like
     #ifdef __APPLE__ and #ifdef __linux__
    
    So this patch adds a TRADITIONALCPPFLAGS variable which contains just
    -traditional where applicable without the other RAWCPPFLAGS for unsetting

    Use the right variable names for the compiler flags in XORG_TESTSET_CFLAG
    
    Whilst populating the xorg_cv_ cache entries, and the subsequent
    xorg_testset_, we always include the FLAG_PREFIX in the name, to
    distinguish between C and C++ iterations. However, in the body of the
    test function, we dropped the FLAG_PREFIX expansion and so always used
    the empty string and hence did not correctly detect incorrect flags.

    Separate unknown warning options by language
    
    If XORG_COMPILER_FLAGS is called more than once with separate languages,
    the unknown warning options used internally for unknown warning checking
    will be set the first time and then the cached value will be used for
    subsequent languages. This is a problem if the compilers differ between
    the languages.
    
    This change ensures that the unknown warning options are namespaced so
    multiple XORG_COMPILER_FLAGS calls with different languages are checked
    separately.

    Don't use AS_ECHO in XORG_TESTSET_CFLAG
    
    Further to commit 52ef6f6, since AS_ECHO isn't supported in autoconf 2.61 either,
    rewrite use of cache variable in XORG_TESTSET_CFLAG so 'echo' isn't needed at all.

    This macro enables a builder to enable/disable integration testing
    It makes no assumption about the test cases' implementation
    Test cases may or may not use Automake "Support for test suites"
    
    Unit test support usually requires less dependencies and may be built
    and run under less stringent environments than integration tests. Thus,
    two separate options for unit and integration testing is desirable.

    Cache the results of checking compiler flag support in XORG_TESTSET_CFLAG
    
    Since checking all those warning flags takes an amount of time I find irritating,
    here is an attempt at caching the results of checking compiler warning flag support
    
    A couple of aspects which need definitely need review or testing:
    
    * I've tried to get things right when not the first flag in the list of alternates is
    supported, but this really needs testing with a compiler other than gcc
    
    * The cache variable naming policy is a bit opaque me, so the names used may need corecting
    
    * I've tried to be careful, but who knows what portability sins I have committed :-)
    
    This change reduces the time to run the ./configure script produced from a configure.ac
    containing just
    
    AC_INIT([test], 1.0)
    XORG_COMPILER_FLAGS
    XORG_CWARNFLAGS
    XORG_STRICT_OPTION
    AC_OUTPUT()
    
    from ~60s to ~20s on my cygwin machine, and from ~15s to ~9s on a linux VM running on the
    same hardware
    
    v2: AS_TR_SH transforms characters which are invalid in shell variable names, so we don't
    have to use sed to transform spaces ourself

    XORG_WITH_FOP: add minimum version checking support
    
    Adding this feature is motivated by a bug in fop 0.95 where
    fop crashes in the presence of some characters like the latin capital
    sharp s. Fop version 1.0 works correctly.
    
    This is the same feature found in XMLTO and the likes.
    In the macro public interface there is a shift in parameter position
    for the DEFAULT parameter. Doing development on older libraries
    (point releases on older versions) will still work the same way as
    the "no" value will be interpreted as the minimum version. It won't
    be found, so fop will be disabled anyway.
    
    Only libX11 has used XORG_WITH_FOP(no) and will be changed with a version
    bump on util-macros.

    XORG_WITH_GLIB([MIN-VERSION], [DEFAULT])
     ----------------------------------------
     Minimum version: 1.13.0
    
     GLib is a library which provides advanced data structures and functions.
     This macro enables a module to test for the presence of Glib.
    
     When used in conjunction with XORG_ENABLE_UNIT_TESTS, use both AM_CONDITIONAL
     ENABLE_UNIT_TESTS and HAVE_GLIB.
     Glib may be used for purpose other than testing
    
     Package builders should use --without-glib to ensure it does not get pulled in.
     Unit tests may or may not use GLib.
    
     Developers should use --with-glib to error out if GLib is missing.
    
     Interface to module:
     HAVE_GLIB: used in makefiles to conditionally build targets
     with_glib: used in configure.ac to know if GLib has been found
     --with-glib:   'yes' user instructs the module to use glib
                    'no' user instructs the module not to use glib

    XORG_WITH_XSLTPROC: add XSLT processor command line tool
    
    The primary use will be for DocBook/XML cross links database generation.
    
    XSLT (Extensible Stylesheet Language Transformations) is a declarative,
    XML-based language used for the transformation of XML documents.
    The xsltproc command line tool is for applying XSLT stylesheets
    to XML documents.
    
    It is used under the cover by xmlto to generate html files from DocBook/XML.
    The XSLT processor is often used as a standalone tool for transformations.
    It should not be assumed that it is used only to work with documnetation.
