Re: [ros-dev] Let's push winetests farther!

[Jérôme Gardou]

I do get this error too, but that does not stop me from doing some 
tests. What I did was to recompile kernel32 as kernel32_test and link 
the winetest to it instead of kernel32, and launch it in winXP. This 
sounds really dirty as it is, but gave me good result. The fixed tests 
on reactos side was a mistake.
