Hey everyone,
Although I'm a student again, I don't really have the time or chops to apply for GSoC, at least not this year. I was randomly looking up things the other day though when I came across precompiled headers. I don't remember seeing any sight of them when I studied wine code in the past, and all I found on the mailing list was this: https://www.winehq.org/pipermail/wine-devel/2004-July/027933.html
It might not be a hard-enough task to warrant a GSoC grant, and I don't know enough about the details to add an entry to the wiki (Would precompiled headers work for wine? Does wine actually use them already?) I just thought I would mention it because if it makes sense for the project, it might be an interesting change with a big payoff for build times.
