Wine conformance tests with MSVC headers

[Vincent Béron]

Hello,

I tried to compile the various conformance tests with MSVC 6.0. There 
are two different configurations for each project: with MSVC or Wine 
headers. With the MSVC headers configuration, it doesn't find 
"wine/test.h" (since wine/include is not in the include path). Is it a 
known behavior? With the Wine headers configuration, I don't get those 
errors (but there are a bunch of warnings concerning signed/unsigned 
comparisons, for which I'll try to send a patch tonight).
