wine-20040213 doesn't compile on Linux w/ 2.6.3 kernel and gcc-3.3.3

[P. Christeas]

I had found the same problem, and now compile Wine with 2.6.x ..
This is a kernel problem, wine doesn't need to be modified at all. There was 
indeed a trivial patch at lkml, but hasn't still been applied (i wonder why).
First of all, you should *not* compile any userspace program with the 
__KERNEL__ flag. These headers need to know that they aren't being used by 
the kernel code.
The problem is that the scsi headers (and cdrom AFAIK) use the kernel 
definitions of types, not the global ones. The kernel looks like '__u16' 
while the global is 'u16' etc. Since the headers are meant to be used by 
userspace programs, they should have been using the global (like 'u16') ones.

It's therefore IMHO absolutely safe and sound to patch your kernel headers and 
replace these types. Then, wine and others will compile correctly.
