Convex defines the nlist struct somewhat differently than Sun or Stellar
(I'm not familiar with other Unix dialects):

struct nlist {
	union {
		char	*n_name;	/* for use when in core */
		long	n_strx;		/* index into string table */
	} n_un;				/* union for name and string index */

	unsigned char	n_type;		/* type flag, see below */
	char		n_other;	/* unused */
	short		n_desc;		/* see <stab.h> */
	unsigned long	n_value;	/* value of symbol (or sdb offset) */
};

The compiler complains about the use of n_name when compiling load.c, so I
changed load.c to reflect this for the Convex. If this is a feature of more
than just Convex's environment a more general test is in order.
