Right now, we have 15 exported headers [1] that use the non-strict 
posix types (pid_t, off_t, clock_t, ...) and a set of 106 (!)
files [2] using non-strict integer types (u_int32_t, uint32_t, u32, ...),
76 of those alone in netfilter.

Do you think we should fix up all of them before 2.6.29? I'm worried
that we might introduce more regressions in the process.
Also, should we leave netfilter alone, in order to reduce the changes?
I'm also unsure whether a hack in headers_install would be better than
changing the headers in the source tree.
