This is easily fixed:

09:58:20 [ruby]: /cygdrive/c/temp/ruby/pfile.rb
["/cygdrive/c/temp/ruby/pfile.rb", "/cygdrive/c/temp/ruby/pfile.rb"]
09:58:31 [ruby]: ./pfile.rb
["./pfile.rb", "/cygdrive/c/temp/ruby/pfile.rb"]
09:58:38 [ruby]: ruby pfile.rb
["pfile.rb", "/cygdrive/c/temp/ruby/pfile.rb"]
09:58:40 [ruby]: cat pfile.rb
#!/usr/bin/ruby

FILE = File.expand_path __FILE__

p [__FILE__, FILE]
