glibc 2.1.92 compatibility with glibc 2.1.3 ?

Hi,

Is glibc 2.1.92 binary compatible with glibc 2.1.3? 

Should the symbol getrlimit64 version GLIBC_2.1 be present in glibc 2.1.92?

[root@localhost local]# cd /space/src/glibc-2.1.92
[root@localhost glibc-2.1.92]# nm libc.so.6 | grep getrlimit
000cef48 t __getrlimit
000cef48 t __new_getrlimit
000cf024 t __new_getrlimit64
000d60c8 t __old_getrlimit
000d5f78 t __syscall_getrlimit
000cf024 T getrlimit64@@GLIBC_2.2
000cef48 T getrlimit@@GLIBC_2.2
000d60c8 T getrlimit@GLIBC_2.0

Shouldn't the symbols of glibc-2.1.3 be a perfect subset of the symbols defined
in glibc-2.1.92 and if not why not?

Thanks,

Kevin
