According to Bingo at avrfreaks.com ...

1 : Backup/Copy your <WinAVR>/avr directory to a safe place ,
     or at least the "lib and include" directories within the <WinAVR>/avr 
directory.
     As they are going to be overwritten (deleted) following this procedure.


2: Unzip the avr-libc-bin-1.2.6.zip somewhere , it will make an 
avr-libc-bin-1.2.6 directory that contains
    three directories named bin,lib and include. The lib and include contains 
the new avr-libc (in lib) ,
    and the corresponding header files (in include) , in bin is some kind of manual.

3: MAKE sure you did step 1 !!!!!!!

4: In the <WinAVR>/avr directory , delete or move the two directories named lib 
and include ,
    so you will end up with just a bin directory.
    You still need the bin directory , as that is where the avr tools and the 
compiler is located.

5: Now copy the three direct ories from step 2 , into the <WinAVR>/avr directory 
so you now have
    3 directories within <WinAVR>/avr. You should have bin , include and lib in 
there.

6: Copy the ldscripts directory located in your Backup/Copy" avr/lib directory , 
to the new 1.2.6 avr/lib directory
    the ldscripts dir gets installed with binutils , and is not a part of 
avr-libc , but is needed by the linker.

7: You are now done , installing the new avr-libc

8: You are urged to get the avr-libc documentation and read it.
    Get it from the link in the top.

9: If you want to get back to the original avr-libc , then do step 4 , and 
restore the files mentioned in step 1 ,
    into the <WinAVR>/avr directory
