I'm not exactly sure why and how the build error popped up now, but the GTK-specific argument coders were simply not included (anymore?) in the WebPageProxyMessageReceiver.cpp file. This should fix it for good, but I want a review to asses whether it might not be an appropriate approach.

Seems probably not the right approach. ArgumentCodersCF.h and ArgumentCodersMac.h don’t work this way.

Why not simply including ArgumentCodersGtk.h from the sources which need it?

Or including it from only ArgumentCoders.h and adding a guard to avoid
including it from anywhere else.

ArgumentCoders.h is included in ArgumentCodersGtk.h too.

Ah, WebPageProxyMessageReceiver.cpp is a generated source, so it isn't so easy
to fix the generator properly.

I found the root of the problem. Before r177795 ArgumentCodersGtk.h was
included indirectly: InjectedBundleUserMessageCoders.h -> WebPage.h ->
ArgumentCodersGtk.h. But now InjectedBundleUserMessageCoders.h isn't
included anymore.

Committed a fix in r177832.
http://trac.webkit.org/changeset/177832

I just moved the ArgumentCodersGtk.h inclusion from WebPageProxy.cpp to WebPageProxy.h, which makes ArgumentCoder<WebCore::DragData> available in WebPageProxyMessageReceiver.cpp.
