Yes, I have failures due missing guards (platform_is / platform_is_not)

Most of the times is due missing guards and sometimes is missing lot
of Windows specific code.

Please see my rant at the bottom [1]

Hmn, sounds hardcoded, for comparison, file/expand_path_spec.rb:

  before :each do
    platform_is :windows do
      @base = `cd`.chomp.tr '\\', '/'
      @tmpdir = "c:/tmp"
      @rootdir = "c:/"
    end

    platform_is_not :windows do
      @base = Dir.pwd
      @tmpdir = "/tmp"
      @rootdir = "/"
    end
  end

Which is used later on the specs.

If that is hardcoded somewhere, is wrong and needs to be corrected. I
will happily fix that if you open an issue here:

If you're used to a tool, getting full to speed and covering those
guards inside other tool can be time challenging and hard work, sure.

Now, my rant [1]

I'm trying to see if I can improve Ruby performance on Windows, and is
really hard to find ANY documentation on the behaviors of certain
methods.

I was expecting see some test for File.expand_path inside
test/test_file.rb but there is none, except a few in test/sample.rb,
not to mention the lack of result taint testing or encoding.

So, under Windows, neither test/* or RubySpec solves the problem.
However, there are *some* specs in RubySpec that did help me more than
4 regex validations that I found in test/sample.rb

But honestly, nobody from core really "care" to improve this on
Windows and the few that use Ruby on Windows don't have the time to
dig into Ruby C code and extract what is the expected behavior of Ruby
to add to RubySpec.
