    cdefs.h: Retire __const and __signed
    
    These are no longer used in the base system. Once upon a time they were
    used to ease the transition from K&R to ANSI C. These days, we use both
    of these keywords in their bare form everywhere, even in our
    headers. Any uses of __const or __signed will be converted to their ANSI
    meaning in the compiler, but is beyond the scope of cdefs.h's
    charter. For pure K&R compilation, with an enforced only use K&R
    features and meanings, one needs to define NO_ANSI_KEYWORDS (though even
    that support is wobbly at best, being active only for !GCC or
    gcc-adjacent compilers which currently appears to be none).
