Patch options:
1. glibc-2.1.3-idns.tar.gz		patched glibc source
2. glibc-2.1.3.patch			patch file for glibc source
3. libc.so				libc binary file

1. Patching glibc-2.1.x using glibc-2.1.3-idns.tar.gz
   * extract glibc-2.1.3-idns.tar.gz into appropriate directory
     tar -xzvf glibc-2.1.3-idns.tar.gz
   * go to source directory and configure for compilation
     cd glibc-2.1.3
     ./configure --prefix=/usr --enable-add-ons=crypt,linuxthreads
   * compile the source file (this should take quite a while)
     make all
     make check

   * install the patched glibc into system
     make install

2. Patching glibc-2.1.x using glibc-2.1.3.patch
   * get the glibc source and add-ons frm GNU site.
     glibc-2.1.3.tar.gz
     glibc-crypt-2.1.tar.gz
     glibc-linuxthreads-2.1.3.tar.gz

   * extract those source files into appropriate directory.
     tar -xzvf glibc-2.1.3.tar.gz
     cd glibc-2.1.3
     tar -xzvf glibc-crypt-2.1.tar.gz
     tar -xzvf glibc-linuxthreads-2.1.3.tar.gz
   
   * go to the parent directory of source directory and apply the patch file
     patch -p1 < glibc-2.1.3.patch

   * go to source directory and configure for compilation
     cd glibc-2.1.3
     ./configure --prefix=/usr --enable-add-ons=crypt,linuxthreads

   * compile the source file (this should take quite a while)
     make all
     make check 

   * install the patched glibc into system
     make install

Patching glibc-2.1.x using libc.so, libresolv.so, libnss_dns.so
   * extract glibc-2.1.3-binary.tar.gz into appropriate directory.
     tar -xzvf glibc-2.1.3-binary.tar.gz	
   * replace "/lib/libresolv-2.1.x.so" with "libresolv.so"
     cp libresolv.so /lib/libresolv-2.1.x.so
   * replace "/lib/libnss_dns-2.1.x.so" with "libnss_dns.so"
     cp libnss_dns.so /lib/libnss_dns-2.1.x.so
   * copy "libc.so" to "/lib" directory
     cp libc.so /lib/.
   * make the symbolic link "/lib/libc.so.6" point to the replaced library
     ln -fs /lib/libc.so /lib/libc.so.6
