    README: added a sample xorg.conf for 1024x600 and 800x480 laptops.

    config: The compiler version to use is now set in XORG_DEFAULT_OPTIONS
    
    In this case "now" means a couple of years ago. All of Xorg is compiled
    with AC_PROG_CC_C99. It shows up in config.log as CC='gcc -std=gnu99'.
    
    The removed statement was resetting the compiler to C89 as it comes
    after XORG_DEFAULT_OPTIONS.

    config: remove a few dead/obsolete lines of code
    
    HAVE_XEXTPROTO_71 not used in Makefile.
    AC_HEADER_STD is very obsolete.
    AC_SUBST([XORG_CFLAGS]) is redundant.
    DRIVER_NAME is correctly no longer used.
    AC_SUBST([moduledir]) has just been moved up.
    
    Any erroneously removed statements above would result
    in a configuration failure.

    Move back ztv with geode driver
    
    Now we have a clean separation between CPP flags and C Flags
    Only the C Flags apply to both geode and ztv driver, however
    it is not worth doing a per target compilation.
    
    Should some flags become mutually exclusive and if we want to have
    both target in the same makefile, add the incompatible flag
    on the appropriate target, example:
    
    geode_drv_la_CFLAGS = $(AM_CFLAGS) -newCFlag
    and/or
    geode_drv_la_CPPFLAGS = $(AM_CPPFLAGS) -newCPPFlag
    
    Note that both AM_CFLAGS and AM_CPPFLAGS are picked-up by both
    geode and ztv driver target.

commit ac99bf2c5cdf86f039a290397614ca042a56c8db

    Detect 32bit support on 64bit OS and compile with -m32 if found
    
    For gcc compiler only at the moment.
    The configuration reports if support is found or not, e.g.:
    
       checking if gcc supports the -m32 Intel/AMD option... yes
    
    The configuration C test relies on #include unistd.h which includes
    features.h which includes gnu/stubs.h which includes gnu/stubs-32.h
    which is missing on 64 bit system without the 32 bit library support.
    
    Tested on x86_64 AMD64 CPU with/without libc6-dev-i386 which provides
    32 bit support. Remains to be tested on Geode and FreeBSD 32/64 bit.
    
    The configuration does not attempt to decide if building should proceed
    or be aborted. If no 32 bit support then the build will die in the
    assembly code as it always did before.
    
    The variable M32_CFLAGS provides the flag for the makefiles.
    The variable names and organization is subject to change.

    Remove unused and misleading I386ARCH configuration code
    
    The AM_CONDITIONAL I386ARCH is not used.
    
    The AC_CHECK_DECLS is misleading as it suggests there could be some i*86
    system with a 64 bit architecture which is incorrect.
    It also provides false results on 64 bit computer.
    
    The generated HAVE_DECL_XXX are not used anyway.

    Remove duplicate warning variable and werror option
    
    Use already existing:
      --enable-strict-compilation
                              Enable all warnings from compiler and make them
                              errors (default: disabled)
    which, byt the way was broken as it was not implemented in geode.
    
    Use already existing CWARNINGFLAGS variable, so there is no need
    to define GCC_WARNINGS.
    
    Both come from util-macros version 1.4 or later.
    http://cgit.freedesktop.org/xorg/util/macros/tree/xorg-macros.m4.in
    ?id=03b04a6b5d61aafbd2705f7d29e58e0c92553a4a
    
    If you configure with a later version of util-macros you may see new
    warnings appear as additional flags have been added over the years.
    
    You get better support for platforms/compiler differences.

    Remove broken duplicate visibility configure option
    
    This was added by commit f762b456 in 2007 and has been since implemented
    in the server which returns it in XORG_CFLAGS
    
    pkg-config --cflags xorg-server
    
    The server also takes care of platforms and compilers being used.
    Currently the visibility is set twice and even if you disable it,
    it is still passed through XORG_CFLAGS.

    Add a configure option to enable/disable building the ztv driver
    
    Even when V4L2 is available there are always reasons why distros
    may not want to build the driver.
    
    This patch uses a common idiom in xorg.
    When no configure option is specified ztv is built iff v4l2 is detected (auto).
    When user issues --disable-ztv, the ztv driver is not built (no)
    When user issues --enable-ztv, the ztv driver is built (yes) if v4l2 is detected
    but the configuration fails if v4l2 is missing. Distros do not want silent
    failures when a feature is explicitly requested but cannot be built.

    Move ztv driver to it's own directory
    
    The convention is to have the video driver (geode) in the src subdir
    and any other targets (utils, apps, other drivers) in their own
    directory. It makes it much simpler to right a correct makefile
    and to set conditional compile.
    
    This highlighted a few things to fix. For now, the directory includes
    have not been copied as they are required. The AM_CCASFLAGS is not required
    either as there is no assembler.
    
    Other than that, the gcc command issued has no differences. Other unrequired
    defines could be removed later.
