Old kernels and new compilers

a shiny new, and rather internally different, GCC to build them correctly?

gcc has an excellent automated testsuite.

linux does not have an official testsuite, and the existing
test projects are only moderately successful at covering the
set of strange, unexpected, and intentionally malicious
scenarios that may be faced by an OS kernel

For regular code, this is probably ok, but for kernel code?

When there is a major revision of gcc, if memory serves, the Linux kernel breaks in various ways..
