long time no see... Glad to see you Egon

To get a long story short...
- I noticed that there is not ruby 1.9 for cygwin (yet)
- I noticed this when the example given in the "bible", p21 didn't work
- I tried to use the ruby 1.9 windows installer verson in cygwin (I want to have a powerfull and usefull shell, not the windows cmd.exe crap), some of my tests suddently failed!
- I decided to setup a VM. And this took muuuuuuuch longer then I expected....
- but still, some of my tests still fail! GRRR!
- next time I will look at regexp_test.rb, hash_test.rb, open3_test.rb
