I forgot to say, since I'm looking on at Linux, I didn't import the code specific for the other platforms.

I noticed some references to test_runner which is define in a file not included: I've removed or commented them.

To be correct, I still cannot compile on Linux, but at least it doesn't introduce more errors.

The only change here is I've renamed appshell/cefclient_gtk.cpp → appshell/cefclient_gtk.cc (notice the extension) to match the cefclient example code

I could include all these files on other platforms but on Windows I had some problems compiling files with same name (appshell/client_app.h and appshell/common/client_app.h for example)
