Too many. Alas I can't share them. However, your input is most welcome, and that
grep shows that my regexp is *way* too broad. So auto-NACK-ing, and I'll now work
on something that doesn't include most of the above hits. Suggestions for a regexp
banning the fake typedefs that would get flagged were they to be mapped onto a 
typedef would be most welcome. The context I'm seeing them is a clear checkpatch
avoidance mess, and I'd like to see it similarly flagged.

Cheers,
Phil
