: 3. Lets better store everything in exports.h. You can add a new
: section in this file separated by a comment, that these symbols are
: from ICU, to not scatter them among other exports. Also please sort
: the exports in the alphabetical order, as it is asked in exports.h
: comment.

Agreed with Vlad here - keeping all inside of single exports.h would make 
this code much, much easier to maintain. I'd recommend you to return back 
to the original idea with using special EXPORT_ICU(name) macros which would 
expand to EXPORT(U_ICU_ENTRY_POINT_RENAME(name)) _iff_ not U_DISABLE_RENAMING
and to EXPORT(name) otherwise.

And for +#if U_ICU_VERSION_MAJOR_NUM >= 51 I'd suggest (but not insist) to 
create yet another wrapper EXPORT_ICU_51UP(name). This would make it looks 
very consistent with others. Though with 1 usage case it might be overkill.
