https://bugs.ruby-lang.org/issues/10458#change-49742

* Author: Martin D端rst
* Status: Open
* Priority: Normal
* Assignee: Nobuyoshi Nakada
* Category: build
* Target version: current: 2.2.0
* ruby -v: ruby 2.2.0dev (2014-10-30 trunk 48194) [x86_64-cygwin]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
When I did
   make up; make install-nodoc
after r48196, make finished with the messages below. This was after the three Unicode data files had been downloaded correctly into enc/unicode/data/7.0.0 earlier in the make process.

I know that the idea of creating separate directories for separate Unicode versions was discussed at the meeting yesterday. But I think it is unnecessary, and may lead to some people keeping lots of old data around when it could be overwritten. It would be better to note the version/data in a very small file, as discussed at https://bugs.ruby-lang.org/issues/10416#note-3.

These are the error messages I got (only the end of the output is copied).
