Given the choice between inventing our own 'nil pointer' type and thus
deviating from the entire body of C code written ever, and working
correctly on systems which define NULL as a pointer-cast zero value
(and thus getting appropriate integer/pointer mismatch warnings on
relevant compilers), we're taking the latter.
