Hello,

I am trying to compile tacacs+ with skey support however there is difference in definition of skeychalleng function.

Tacacs+ try to pass 4 arg to the function

[root at TACACS tacacs+-F4.0.4.19]# grep skeychallenge skey_fn.c 
	    if (skeychallenge(&p->skey, name, skeyprompt, 80) == 0) {
=====================================================================

while function definition expect only 3 arg
=====================================================================
[root at TACACS skey-1.1.5]# grep skeychallenge *.h
skey.h:int skeychallenge(struct skey * mp, char *name, char *ss);
