Hello Huw,
yes please revert.

Right now Wine version of RegEnumValueW supports being called with 
parameters value and val_count being NULL.
(And is used that way at least in 
systemfontfileenumerator_GetCurrentFontFile.)

The Microsoft implementation unfortunately does this not.

Right now I am trying to find the places in Wine code and try to change 
them in a Windows compatible way. Later another patch could change 
RegEnumValueW to check these two parameters.

Should I have sent this ignore request to wine-patches instead/also?

I am very sorry to cause this trouble.

Kind regards,
Bernhard
