I couldn't figure out how to pass an array of pointers to sprintf()
and make it work correctly, but here's a dippy way that does work.

 #include <stdio.h>
 #include <varargs.h>
 main()
 {
 	dialog("%s\t%s\t%s", "one", "two", "three");
 }
 char *
 dialog(format,va_alist)
 char *format;
 va_dcl
 {
 	va_list ap;
 	char *args[10];
 	char buffer[512];
 	int argcount = 0;
 	
 	va_start(ap);
 	while((args[argcount++] = va_arg(ap, char *)) != (char *)NULL)
 		;
 	va_end(ap);

 	sprintf(buffer,format,args[0],args[1],args[2],args[3],args[4],args[5],args[6],args[7],args[8],args[9]);
 	printf("%s\n",buffer);
 	return(buffer);
