since you cant run and therefore cant debug / step / break points etc. I see little point. beyond hello world.
basically you're using lazarus as a syntax aware editor.
wine is a long, long , long way from an accurate emulation of win32 so any run on wine is of little relevance as a test bed.
Apart from that delphi/laz is a nice editor and if, like me, you are familiar with it , it can be a good tool.
I used it to edit the C source for some patches I submitted for gtk2 filechooser.
