Yes, that's why I used a wine_skip() rather than a skip(). I think this 
approach is valid too. My understanding is that in theory 
CLSID_WebBrowser could be provided by any other dll. So given that this 
test makes no direct use of ieframes.dll (that is does not link with it 
nor loads it at run time), that makes checking for the presence of 
ieframes.dll a bit questionable.

Indead on my NT4 VM I do get a CLSID_WebBrowser object but various tests 
then fail. It appears the same thing happens on the W2KPROSP4 testbot 
VM.

I presume that's because these Windows versions provided this object 
through some older dll that did not support everything. But it would be 
nice to have the tests detect that and win_skip().
