    Use the Automake recommended alternative to AX_DEFINE_DIR
    
    DATADIR, like any installation variable, is not known at configure time.
    This is by design to allow setting the variable at make time.
    The AX_DEFINE_DIR macro worked around this design and consequently
    cancelled an Automake feature.
    
    The alternative method suggested by Automake ends up being simpler
    while providing the same result as AX_DEFINE_DIR but without cancelling
    any feature. It is used in the xserver for the parser and in xquartz.
    
    The AX_DEFINE_DIR macro has been removed from the Autoconf Archive.
    There are no official providers for this macro anymore.
    
    Separate pre-processor from compiler flags.
    XFD_CFLAGS and CWARNFLAGS may contain compiler flags.
