Implications of using g++-3.0

[Ross Boylan <RossBoylan@stanfordalumni.org>]

If I use g++-3.0, do I need to build most of my own libraries?
For example, I wanted to use libstrutilsxx, but it didn't work.  I
think I read (though I can't find it) that object files from different
versions of the compiler can't be mixed.  True?

Since 2.95 is the default (i386 woody), all the debs are built with
that, so they won't work with 3.0, right?

(I'm hoping I'm wrong here!)

I tried getting the source and compiling for the library, but it
didn't work.  This was puzzling; perhaps it uses some language feature
that changed?  The problem seemed to be with streams; I haven't had
time to track it down.

Anyway, if all this is true, maybe I should go back to 2.95.  I
understand it doesn't implement the standard fully, and I was hoping
to avoid getting into that swamp.

Thanks for any advice.
