libc changes and freebsd-4 compatible binaries

[Yury Tarasievich <grog@xxxxxxx>]

The level of discussion is well beyond my competence, could somebody offer 
clear explanation -- will freebsd-4 compatible binaries continue working on 
current DFBSD? E.g., Opera is still building their packages for 2.95.4 and 
libc.so.4 and there are lots of packages I'm using off-the-site and wouldn't 
ever bother to recompile them. So, what about it? Thanks.
