Re: [ros-dev] Re : compatibility vs. correctness

Wine test have helped me many times found bugs in our gdi32
I rember frist time I run it. it crash whole ReactOS after that
I started fixed each crash. After that I try fix bug after bug
that wine test show in gdi32. without them it should have
taken longer time to found some bugs or some bugs should
simple be missed. I say wine test is good, and real usefull.
But some test does not work on XP but works on 2000
same goes with VISTA. it show how stuff work diffent or
been broken also on windows betwin diffent version.

Aren't Wine tests based on a personal preferred behaviour (not really
sticking to windows in some cases) or MSDN ?
It would render them unreliable too.
 Kind regards,
