    # Additional variant settings, to be combined with nonstop-common
    # Note that these do not inherit anything.  However, the diverse values

    # These combine:
    # - System architecture (MIPS, Itanium, or x86)
    # - Execution environment (oss [default] or guardian)
    #
    # Unfortunately, they can't be separated into independent templates, because
    # a number of the above are encoded as different linkers, and by consequence,
    # different c99 linker flags (-Wld, -Weld, and -Wxld)
    #
    # In addition, the are modifiers for:
    # - Size of long + pointer (ilp32 [default] and lp64)
    # - Float type (neutral and tandem)
    #
    # Unfortunately, because the float types affect the linker settings, those
    # are divided per system architecture
