This fix goes in telnet.c (or maybe tn3270.c, if you are using an
older version). tn3270 (and telnet, for that matter) were using
a "varargs" routine without using the "varargs" mechanism.

Replace the routine "call()" with the code below.

Sorry, about that.

Greg Minshall

 * Call routine with argc, argv set from args (terminated by 0).
#include <varargs.h>
    va_list ap;
    typedef int (*intrtn_t)();
    intrtn_t routine;
    char *args[100];

    int argno = 0;

    routine = (va_arg(ap, intrtn_t));
    while (args[argno++] = va_arg(ap, char *))
    return (*routine)(argno, args);
