First of all thanks for reviewing the test!

MSDN states that:
cVersion Specifies the operating system version for which the driver
was written. It can be one of the following.
Value    Meaning
0        Driver for Windows 95/98/Me.
1        Driver for Windows NT 3.51.
2        Driver for Windows NT 4.0.
3        Driver for Windows 2000/XP.

Since Wine by default reports either win9x or win2000/XP I've chosen
to report 0 or 3, I don't think there is any app that depends on
a particular value.

Feel free to add a test for that and fix it.

PDRIVER_INFO_2W is the lowest denominator for all extended structures,
I think it's more correct to use it.

Feel free to adopt the test to handle an error in that case and not report
a failure.

I don't see much point in that.

All the tests in Wine I write and most others use 0xdeadbeef directly,
that way I don't need to inspect the whole file to see to which value
that magic macro is defined.

I'll have a look once the test results appear on test.winehq.org/data,
but feel free to make the test fail more gracefully on that platforms.
