And another note (after looking at the Cc list):

Header cleanup is *not* something suitable as a first task for a janitor.

The interesting cases are non-trivial.

And you need cross compilers for all architectures since fiddling with 
#include's under include/ breaks code left and right that only compiled 
due to some implicit #include (and if it still works due to another 
implicit #include on x86 the latter might not be present on all 
architectures).
