ls -i vs. stat()

I have noticed that 'ls -i' is giving different i-numbers for linked
files, while stat() says that they are the same. This was noticed on
SunOS 4.0.3.
The man page for 'ls' says:
-i For each file, print the i-number in the first column
of the report.
The simple program I that called the stat() system call did this:
stat(filename,&sbuf);
printf("\ti-number = %-10d %s\n",sbuf.st_ino,filename);
Running a simple test:
$ stattest stat.c
i-number = 2953 stat.c
$ ln -s stat.c stat.link
$ stattest stat.*
i-number = 2953 stat.c
i-number = 2953 stat.link
$ ln -i stat.*
2953 stat.c 38379 stat.link
Is this the correct output for the 'ls -i' command? I would expect all
links to have the same i-number as the original.
Any help appreciated,
