This needs more investigation. Some extra testing showed that LastError
is not always set by the calls (all?). 
I added traces to all the calls and suddenly nothing was implemented
anymore. Then I added a SetLastError(0) before every call and the output
was totally different again. The only thing not implemented anymore on
my win98 box was SystemParametersInfoW.

So what's the best approach:

- add a SetLastError(0) in every test-routine before we do something?
- add a trace after each SystemParametersInfo call?
- find out which call sets LastError and which calls don't?

Cheers,

Paul.
