The problem is things like u64 etc that is VERY common in all headers, but then again __u64 etc are just fine, history has proven that already.

Agree. But to be on the safe side one can use uint64_t and friends (which the kernel can typedef to u64 and first degree relatives)

Now that the kernel no longer targets gcc before 3.2, c99 names are merely ugly rather than an actual problem. :)

No, they're still a problem in ABI headers because they have defined visibility. A userspace program that does not include <stdint.h> will not have those types put in its namespace. Including <sys/ time.h> _cannot_ bring <stdint.> in automatically, that breaks the POSIX symbol visibility rules.
