[WinCairo] Fix build errors which come from including headers and not suitable implementation for windows

• Status: RESOLVED FIXED

[Yousuke Kimoto]

For WinCairo WebKit build, some build errors which come from including headers must be fixed.
Those headers are not supported by the Windows SDK.

A patch for bug 182681 is required before landing this patch.

Fixed the #include guard in WKBase.h.

Seems like something other than the C preprocessor is running over this file, so even `#if 0` doesn't remove anything. #elifs did the trick though.

Style: please move these down beneath the other #includes, and leave one blank like before #if !OS(WINDOWS). You got it right *almost* everywhere else.

Here too.

OK. Since there are no changes to the cross-platform code, I don't think this needs an owner. Consider adding FIXMEs for the stuff you've disabled in NetworkCache.

This causes an iOS build failure for me when building with -Wunused-lambda-capture:

Sources/WebKit2/NetworkProcess/cache/NetworkCacheStorage.cpp:911:79: error: lambda capture 'maximumParallelReadCount' is not required to be captured for this use [-Werror,-Wunused-lambda-capture]
            traverseOperation.activeCondition.wait(lock, [&traverseOperation, maximumParallelReadCount] {
                                                                              ^
1 error generated.

I will get a patch up removing this capture.

BTW, this should not have been landed as an unreviewed WinCairo fix when it changed platform independent code.

Got it. I was looking at the patch.

[Michael Catanzaro]

Eh, actually I should not have approved it because I'm not an owner. I just missed that that line was changed outside the #if. Sorry.

[Ross Kirsling]

An even more trivial follow-up fix (which I probably should've noticed while helping get this patch landed):
