Bug #3317: test/rake/test_win32.rb does strange tests and reports errors and failures
http://redmine.ruby-lang.org/issues/show/3317

Author: Usaku NAKAMURA
Status: Open, Priority: Normal
Category: lib, Target version: 1.9.2
ruby -v: ruby 1.9.3dev (2010-05-19 trunk 27884) [i386-mswin32]

See the results in the end of this message first.

1):
Why this test assume that ruby expands '~' even if ENV["HOME"] is not available?
All other platforms don't expand it in such case, same as ruby on Windows.

2):
Where this constant is defined?

3):
lib/rake/win32.rb sees ENV["AppData"] first, and only when it's not available,
sees ENV["HOME"].
Which is correct, implementation or this test?

4):
Combination of 1) and 3).
