	I encountered the problem using gcc 2.3.1 on SS2 SUNOS 4.1.2.
	I compiled the folowing program using gcc2.3.1 and cc and run
	under the Openwindow2.0's comannd tool. I expected
	the result is the same, but not.

% cat ttt.c
#include <stdio.h>
#include <stdlib.h>
#include <sys/ioctl.h>
#include <sgtty.h>


#define EXIT_OK 0
#define EXIT_FAILURE 1


main()
{
    struct sgttyb arg;

    if (!isatty(fileno(stdin))) {
        fprintf(stderr, "stdin is not tty\n") ;
        exit(EXIT_FAILURE);
    }
    fprintf(stderr, "tty name is %s\n", ttyname(fileno(stdin))) ;
    if (ioctl(fileno(stdin), TIOCGETP, (char *)&arg) < 0) {
        perror("ioctl - TIOCGETP");
        exit(EXIT_FAILURE);
    }
    fprintf(stderr, "We can do ioctl\n") ;
    exit(EXIT_OK);
}

	The config.status of gcc is the following.

% cat config.status
#!/bin/sh
# GCC was configured as follows:
./configure --target=sparc-sun-sunos4.1 --prefix=/usr/gnu
echo host=sparc-sun-sunos4.1 target=sparc-sun-sunos4.1 build=sparc-sun-sunos4.1

	And the script of the result is the following.

% gcc -v -o ttt.gcc ttt.c

% ttt.gcc
tty name is /dev/ttyp4
ioctl - TIOCGETP: Inappropriate ioctl for device

	And the result of the default SUN cc is the following.

% cc -v -o ttt.cc ttt.c
/lib/cpp -undef -Dunix -Dsun -Dsparc ttt.c >/tmp/cpp.11939.0.i
/lib/ccom - </tmp/cpp.11939.0.i >/tmp/ccom.11939.1.s
rm /tmp/cpp.11939.0.i
/bin/as -o ttt.o -Q /tmp/ccom.11939.1.s
rm /tmp/ccom.11939.1.s
/bin/ld -dc -dp -e start -X -o ttt.cc /usr/lib/crt0.o ttt.o -lc
rm ttt.o

% ttt.cc
tty name is /dev/ttyp4
We can do ioctl


	I hope this information is useful to you.
