Mateusz,

GDAL/OGR is a project that I manage only with Visual C++ 2003.
I don't use makefile.vc, nor nmake.opt.
But I use command lines only to test "gdal.dll" with ogrinfo.exe (that is 
why I call vsvars32.bat).

I think I use in my VC++ project files same options as specified in 
nmake.opt from www.gdal.ogr.
But I am not sure for all flags (you can see in attachement file, if you 
want)

How do I build GDAL :
- I compile/build gdal.dll and ogrinfo.exe with Visual C++ 2003
- I copy/paste ogrinfo.exe and a DGN v7 file in a same folder with gdal.dll
- I call vsvars32.bat in command lines
- I call ogrinfo.exe to verify which file formats supported by gdal.dll 
(ogrinfo --formats)
- I call ogrinfo.exe to open a DGN v7 file (ogrinfo file.dgn)

thank you

Good weekend
Jean-Daniel
