In what way do you think I'm "late"? Relative to the rest of Debian,
aren't you on the "bleeding edge"? If someone in my position was trying
to use 3.4 before the amd64 port had, where would they look? Who would
they ask? </rhetorical>
Anyway, thanks for letting me know about amd64. Tho it didn't really
answer my question - how do you use gcc-3.4, when all the packages
build-depend on gcc-3.3? What I mean is: Is there some indirection to
apply to apt-get/ dpkg-buildpackage, that will make it use a specified
$CC? Specifically, how did you override gcc-3.3 in libc6?
wrt c++, I'm guessing I'll have to go through each failed package, find
the patch and fix it. That's tedious, so isn't there an easier way?

They'll be the ones I'm trying to find. I'm hoping every package will
"make check" itself, and that that will find any compiler bugs, because I
haven't yet figured out a strategy for testing every single line of code
in Debian :)
