For the BUILTINSXP and SPECIALSXP types, the R Internals page documents
"An integer giving the offset into the table of primitives/.Internals. "
What macro gives me the value of this integer? I guess something like
this would work
had R_USEINTERNALS been defined
(where v is a SEXP of either of the above types).
What is the portable version?
