the glibc2/libc6 tale Re: What's the storywith 2.0?
The difference between libc5 and libc6 is in the name "glibc2". Libc5
was predominantly Linux only. libc6/glibc2 is gnu libc. It is
installed (or will be) on systems besides Linux. This makes porting
between unices easier and makes the differences between them less.

incompatible with libc5 -- hence the need to move all apps to it. In
the beginning many apps broke on libc6. Now it is sometimes reversed.
