I do not remember when I upgraded from lenny to squeeze. It the previous
gcc was lenny's, it was gcc version 4.3.2 (Debian 4.3.2-1.1). The gcc in
current stable (squeeze) is gcc version 4.4.5 (Debian 4.4.5-8). Since
the old laptop is somewhat slow for following unstable, I have not tried
any newer gcc version on that machine, and it has been compiling its own
kernels for stress-testing purposes.

So it's probably not related to gcc 4.6->4.7 changes.
