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

[Tom Williams]

Thanks for the info. I tried building wine with __KERNEL__ after I 
posted my message and got past this problem but encountered TONS more so 
that was obviously NOT the solution.  :)

I'll look into doing what you describe below.  :)

Peace...
