First, the generated project is NOT a typical Visual C++ project.
It does not provide any build configuration itself.
It just calls NMAKE and builds whatever is specified in the Makefiles of GDAL.
So, if you do not edit your nmake.opt/nmake.opt.local, then you will
get default Release build.

Yes, because as I explained above, the project does NOT build separately
in Release and Debug subfolders.
Basically, when you hit Build in VS IDE is like you execute
nmake /f makefile.vc command in command line.
Both are equivalent, NO difference.

If you expect fully features .vcxproj, you really need to create it

That is default GDAL nmake.opt setting.

OK, but I'd prefer if you posted it to gdal-dev.
Let's continue further discussion there ('ve CC'ed to gdal-dev).
