[Bug libc/713] New: fgets() should only return zero upon error or EOF

["bww at acm dot org" <sourceware-bugzilla at sources dot redhat dot com>]

/*
 * fgets() should only return zero upon error or EOF
 * (and not having enough space to store all available
 * input is not an error).
 *
 * For example under Fedora Core release 3 ...
 *    % gcc -static c.c -o c
 *    % echo | ./c
 *    ERROR
 *
 * whereas under Solaris 5.8 ...
 *    % gcc -static c.c -o c
 *    % echo | ./c
 *    OK

#include <stdio.h>

int
main()
{
    char buf[1];
    char *bp;

    bp = fgets(buf, sizeof buf, stdin);
    printf("%s\n", (bp == buf) ? "OK" : "ERROR");
    return 0;
