Your compiler is lazy, legally (i.e. just being efficient, unless you asked
for extra checking).  Your lint is broken.  Get a refund for your lint.

No, because "far" is a valid preprocessor token.  The compiler can't
know if you also if'ed out something legal like "#define far unsigned".

Yes, compilers can legally complain about this.
