Oops, sorry about that. As you note, it doesn't really affect  
anything, just looks confusing; anyhow, I'll fix it.

By the way, regarding the other ICU patches you sent, you'll notice  
that I have not applied these. They relate to the regular expression  
engine, but that part of ICU is not used by xetex, so they're  
irrelevant for our build. (And for the future, I expect to update to  
the latest release of ICU at some point -- though certainly not before  
TL'09.)

Regarding the naming of ICU's Features.h, and the conflict with gcc's  
features.h under Cygwin, have you reported this to the ICU project?  
Whenever we import a new ICU release, the problem is liable to return  
unless it is fixed in the upstream sources -- or you find a way to  
resolve it through appropriate setting of #include paths during the  
build. (What does the cygwin port of ICU do?)
