Hmm. I'm note sure I like making unistd.h an optional header but then few part of Wine should include it anyway so perhaps it doesn't matter.
The question is whether you can build without it. If the needed definitions are provided by other includes then it's fine to make it optional; but if the code doesn't compile without it then there's no point in having a check.
