True, but this is the wrong file :-). All systems will have
/lib/libc.so.6 _and_ /lib/libc5-compat/libc.so.5 
The links we're talking about are :
 for libc6-dev: /usr/lib/libc.so
 for libc5-alt-dev: /usr/lib/libc5-compat/libc.so or
                    /usr/i486-linuxlibc5/lib/libc.so 
depending on which directory we chose for the alternative libc5
location.
