Hi!
---

In the includefile arpa/telnet.h it reads ?!

#define	NTELOPTS	(1+TELOPT_NEW_ENVIRON)
#ifdef TELOPTS
char *telopts[NTELOPTS+1] = {
	"BINARY", "ECHO", "RCP", "SUPPRESS GO AHEAD", "NAME",
	"STATUS", "TIMING MARK", "RCTE", "NAOL", "NAOP",
	"NAOCRD", "NAOHTS", "NAOHTD", "NAOFFD", "NAOVTS",
	"NAOVTD", "NAOLFD", "EXTEND ASCII", "LOGOUT", "BYTE MACRO",
	"DATA ENTRY TERMINAL", "SUPDUP", "SUPDUP OUTPUT",
	"SEND LOCATION", "TERMINAL TYPE", "END OF RECORD",
	"TACACS UID", "OUTPUT MARKING", "TTYLOC",
	"3270 REGIME", "X.3 PAD", "NAWS", "TSPEED", "LFLOW",
	"LINEMODE", "XDISPLOC", "OLD-ENVIRON", "AUTHENTICATION",
	"ENCRYPT", "NEW-ENVIRON",
	0,
};
#define	TELOPT_FIRST	TELOPT_BINARY
#define	TELOPT_LAST	TELOPT_NEW_ENVIRON
#define	TELOPT_OK(x)	((unsigned int)(x) <= TELOPT_LAST)
#define	TELOPT(x)	telopts[(x)-TELOPT_FIRST]
#endif <==== !!! ====

Is there any reason for this being different from the definition
of the telnet commands, which reads:

#ifdef TELCMDS
char *telcmds[] = {
	"EOF", "SUSP", "ABORT", "EOR",
	"SE", "NOP", "DMARK", "BRK", "IP", "AO", "AYT", "EC",
	"EL", "GA", "SB", "WILL", "WONT", "DO", "DONT", "IAC", 0,
};
#else  <==== !!! ====
extern char *telcmds[];
#endif <==== !!! ====

#define	TELCMD_FIRST	xEOF
#define	TELCMD_LAST	IAC
#define	TELCMD_OK(x)	((unsigned int)(x) <= TELCMD_LAST && \
			 (unsigned int)(x) >= TELCMD_FIRST)
#define	TELCMD(x)	telcmds[(x)-TELCMD_FIRST]
