I assume everybody knows about Embarcadero ( a.k.a Borland ) and their product: Delphu and C++ Builder. I think that WineHQ could be tested just fine using Delphi Handbooks provided source code + shipped Demos with each RAD Studio release. Why? - I suppose you exceatly can trace what function in what circumstances fails and simply add the function with needed changes to corresponding Header file. I would recommend to use code snipps in: - Mastering Delphi 7.pdf ; - Delphi 2010 Handbook by Marco Cantu and the Code examples, downloadable @ Embarcaderos EDN article. As I am now thinking about possible project using Delphi XE and IntraWeb 11, it would be good testing platform for WInes web capabilities ..
