Description of problem:
I installed updates via yum to FC4 and after that I noticed that libraries 
were changed, because I couldn't even use ls command. I upgraded to FC5 and 
this fixed the libraries, but few important program doesn't work anymore. I 
found this problem by some error messages containing shared libraries file or 
directory not found. Only missing library seems to be libc_2.0 from libc-
2.4.so. I can find that missing piece from old libc.so.6, but when I remove 
the soft link libc.so.6 and replace that with the old libc.so.6 everything 
breaks apart. Ofcourse these libraries aren't compatible by just copying. I 
would like to know how could I import the missing glibc_2.0 support or get a 
patch which would do it for me. I wonder why old libraries are modified on FC4 
update, giving frustrating work. Including this glibc_2.0 support would fix 
the broken softwares. I don't have or can't get the source codes to these 
broken softwares anywhere.

Version-Release number of selected component (if applicable):
libc-2.4.so and libc.so.6

How reproducible:
Everytime.

Steps to Reproduce:
1. Just install FC5 and the library is missing...
2.
3.
  
Actual results:
Error while loading shared libraries, No such file or directory
(missing glibc_2.0)

Expected results:
