nptl configuration

[divij bhatt]

Hi,
    I want to know that how can i configure nptl on my linux 2.6.10
kernel.I am confused little bit because when  I give 
the command:->getconf GNU_LIBPTHREAD_VERSION it is returning the value
nptl-0.61 but when i am giving the command:->
/lib/libc.so.6 where it is giving following output:->linuxthreads-0.10
by Xavier Leroy instead of 
Native POSIX Threads Library by Ulrich Drepper et al I am using the gcc
version 3.3.3 and Thread Model:-POSIX But when I 
am giving:->/lib/tls/libc.so.6 it is giving:->Native POSIX Threads
Library by Ulrich Drepper et al So tell me whether it 
is working or not.

Thanks
