C binary linkage is the same, but the C++ linkage convention
changed. You need to make sure you build and install libstdc++
when you install the new GCC (you must pretty much always do
that). Of course, you need to keep the old libstdc++ around
for any code that's dynamically liked to it and built by
the old compiler.

Chris, I don't think you should be building kernels with GCC 3,
in case you were tempted to try that :-)
