Well, most libraries will require porting (I know I had to do a good
deal of changes to get AweMUD compiling on gcc 3.0) so I believe new
versions of many libraries will be released with "gcc 3.0 compatibility"
as a feature.

So, that solves how to upgrade those libraries: when upstream releaes a
new version that compiles on gcc 3.0, make the Debian package compiled
with gcc 3.0.  But there is then the issue with all the libraries thta
are already compatible, or will be compatible but won't change version
numbers, etc.

Wonderful pain in the arse, no?
