I'm happy doing it, I don't think the Wmain warnings buy anything for the kernel. My main worry is just that some compiler version might not support it at all or similar, and it would cause problems that way. Which is really the only reason why I'd like to narrow it down as much as (trivially) possible. It doesn't sound worth trying to pinpoint exact gcc version, but making it gcc-only would at least narrow it down a _bit_. Linus
