 *
 * where "2" are the component names of the FUNTAB struct (Defn.h)
 * and	 "3" are the accessor macros. [*]: PRIMPRINT(.) uses the eval component
 *
 * printname:	The function name in R
 *
 * c-entry:	The name of the corresponding C function,
 *		actually declared in ../include/Internal.h .
 *		Convention:
 *		 - all start with "do_",
 *		 - all return SEXP.
 *		 - all have argument list
 *			 (SEXP call, SEXP op, SEXP args, SEXP env)
 *
 * offset:	the 'op' (offset pointer) above; used for C functions
 *		which deal with more than one R function...
 *
 * eval:	= XYZ (three digits) --- where e.g. '1' means '001'
 *		X=1 says that we should force R_Visible off
 *		X=0 says that we should force R_Visible on
 *		X=2 says that we should switch R_Visible on but let the C
 *                  code update this.
 *		Y=1 says that this is an internal function which must
 *		    be accessed with a	.Internal(.) call, any other value is
 *		    accessible directly and printed in R as ".Primitive(..)".
 *		Z=1 says evaluate arguments before calling (BUILTINSXP) and
 *		Z=0 says don't evaluate (SPECIALSXP).
 *
 * arity:	How many arguments are required/allowed;  "-1"	meaning ``any''
 *
 * pp-kind:	Deparsing Info (-> PPkind in ../include/Defn.h )
 *
 * precedence: Operator precedence (-> PPprec in ../include/Defn.h )
 *
 * rightassoc: Right (1) or left (0) associative operator
 *
